S5 L1 Glitchy science segments

I list and plot in the long table below the science segments longer than 2048 sec, with standard deviation larger than 1 (amounting to the top 12%), and investigate possible reasons for "glitchiness", following the notes by operators and scimons in the elog.
In the plots below, the blue points are SenseMon range in science segments, the cyan points are SenseMon range in at least State 3, joined by lines. The green vertical lines are science segments boundaries, the red lines are the segment being considered. The horizontal scale is always the start time of the glitchy segment, +/- 6 hours.
The links on dates point to the LLO elog. The segments are ordered in decreasing order of standard deviation (not chronologically).

From inspecting the highest 35 ranked segments, I suggest the following times to be flagged, grouped by what looked to me similar (bad) characteristics:

Start-End	Duration	Table Row #	Reason
828523656-828536365	12709	1	Very bad glitchiness due to misaligned beam on AS1 PD
841277924-841291321	13397	2,3	Very bad glitchiness due to high power operation.
837456840-837468626	11786	5	Very bad glitchiness at the end of a segment, probably due to a strong storm.
816742980-816752854	9874	12	Very bad glitchiness for unknown reason (but cured with TCS).

817207370-817218064	10694	30	Very bad glitchiness, unknown reason.
823328764-823333868	5104	31	Very bad glitchiness, probably due to high useism.
828175034-828182027	6993	33	Very bad glitchiness, unknown reason.
840620280-840635295	15015	6, 40	Bad glitchiness for unknown reason (probably associate with high power). Includes several segments, but it starts in the middle of one.
841097807-841121982	24175	16	Bad glitchiness probably due to high power and high useismic before Ernesto, combined with a bad WFS gain. Segments L1-2961-2971.
842050745-842074651	23906	18	Bad glitchiness due to high power during high useism noise. Segments L1-3082-3083.
826000845-826041719	40874	32, 54	Bad glitchiness, due to high useism.
838946880-838947647	767	8	Dropping range at end segment due to WFS problem.
825703200-825705734	2534	10	Dropping range at end of segment, probably due to WFS1.
840204314-840205590	1276	21	Dropping range at end of segment, probably due to RBS saturation.
845327353-845328553	1200	27	Glitchy start of segment during warmup.
825746414-825751666	5252	17	Earthquake.
842034614-842038684	4070	18	Earthquake.
842045414-842048738	3324	18	Earthquake.

841178132-841232742	54610	9, 35, 61, 130, 208	Large scatter and bad glitchiness due to tropical storm Ernesto. Segments L1-2977-2985.
836810648-837270455	459807	22	Detector running with a bad SPOB Pentek, adn a large SPOB offset.

#	SenseMon	Start - End GPS	Range Mean, Std	Start UTC	Comments
1		828531744 - 828536365	6.1 +/- 3.6	Apr 08 2006 11:42:10 UTC	This segment is taken during commissioning period. After a storm, a lot of glitchiness and saturations. The previous segment is #15 in this table, with a 2.3 Mpc std. The segment is ended by the operator when the range drops to a steady 0.5 Mpc. The ordeal ends for Tuesday maintainance, and a few days without data follow for commissioning. Rana says the next day: "Found that yesterday's glitching problem was indeed mis-alignment on the PD as Harry said. The misalignment gave us a large offset in AS1_Q." There are many inspiral triggers with SNR>8 and up to SNR~2,000, starting at 828523656. If we cluster these triggers with a 10s window, we veto most of them with ASI_CORR LSC overflow flags, but there are a few left, including the first at 828523656, with SNR 11, with no DQ flag nearby. The minute that follows this trigger is the first minute when the SenseMon range falls to 10 Mpc. The KW rate for triggers with significance larger than 50 is in 5% top percentile, for the 6 hr interval containing these segments; see day 154.7 in this plot from Laura's page, also visible as a spike in KW rate before the commissioning break in the L1 Epochs plot, near day 155. I suggest a DQ flag starting at 828523656, until the end of the segment plotted, at 828536365.
2		841278773 - 841282368	11 +/- 3.3	Sep 03 2006 00:32:39 UTC	These are some of the September "high power glitchy times"; the afternoon operator's log mentions problems when increasing the power at night, starting with segment #2994 at 841277924, until the end of segment #2999, 841291321, when the operator lowers the power due to glitchiness. The much cleaner segment that follows, also with higher range, is clear in the plot. The clean segment (#3000) ends an hour later due to an earthquake. The short segment in the middle is #13 in this list, with std=2.4 Mpc. There are many inspiral triggers generated at the noisy times with SNR up to 1,000; most of the loud ones are vetoed by overflow DQ flags, but there are still many left with SNR>10 that are not vetoed. This is one of the first days of the "noisy September" epoch. This day is in the top 1% percentile of KW rates. I suggest a DQ flag for segs with high power at this time, between 841277924 and 841291321.
3		841282616 - 841288957	12 +/- 3	Sep 03 2006 01:36:42 UTC
4		840969501 - 840971606	13 +/- 2.9	Aug 30 2006 10:38:07 UTC	The large standard deviation is due to this being a short segment which ends with a train. There is a L1:TRAIN_LIKELY:v3 flag ACTIVE (840971130-840971606), and several OVERFLOW flags active in the last fews seconds of the segment. I don't think any other flag is needed in this segment.
5		837466230 - 837468626	10 +/- 2.9	Jul 20 2006 21:30:16 UTC	This is the last and worst of several consecutive bad segments, several in this list: #47, (starts 18:20, std=1.7 Mpc), #66, (starts 19:24, std=1.6 Mpc), #124 (starts 20:29, std=1.3). SciMon (Joe Giaime) reports: "Several strong thunder storms passed through this afternoon, complete with very heavy rain and gusty wind, causing several hours of poor sensitivity and frequent AS trips & lock losses. There have also been repeated episodes of the low-frequency excess bumps mentioned above (but not yet understood)." This particularly noisy segment seems to correspond to the peak of the storm, as seen in the 0.03-0.1Hz band in FOM5. There are many inspiral triggers in these segments, some very loud; although the loudest ones in the previous segments are vetoed by OVERFLOW flags, most of the ones in the stormy segment are not vetoed. The rate of KW triggers this day are in the top 5%: see day 258 in the L1 Epochs page. There is a sharp transition in the middle of segment L1-542 (837454853 - 837458600, #47 in this table), at 837456840, t=-2.5 in this segment's plot, when the range first drops for a minute to 6.6 Mpc. That is also the time when the rate of SNR>10 inspiral triggers rises sharply. I suggest a DQ flag starting at 837456840, and ending at 837468626 (the end of the segment plotted).
6		840618157 - 840623170	13 +/- 2.9	Aug 26 2006 09:02:23 UTC	Another glitchy segments follows this one (#40 in this list, starts 12:31, std 1.7 Mpc). This is again a segment with high power and increased glitchiness. Operator's note (D Hoak): "We had a crummy night: ASI was growing through the locks and causing lots of glitchiness. I fiddled with the TCS a bit this morning and hopefully found a happier place". SciMon note (Chiadini): "Rough nightshift, IFO has been very glitchy. " All (!) of the SNR>10 inspiral 10sec clusters in the bad times of these two segments are vetoed by OVERFLOW flags. The KW rates are not particularly high, as seen in the L1 Epochs page (this segment is in day 295). In fact, ASI CORR overflow flags 12% of this segment, some at the beginning (while detector is warming up), but most after 840619181. 50% of these ASICORR overflows happen less than 4 seconds apart. The noisy derived from SenseMon are 840620280-840623170 in this segment, all of the next (short) segments, 840624759-840625717, 840625868-840626427, 840626560-840627349, and 840632580-840635295 (end of the next long segment).
7		835610669 - 835615175	12 +/- 2.7	Jun 29 2006 10:04:15 UTC	The large standard deviation is mostly due to the end of the segment, while riding a train: L1:TRAIN_LIKELY:v3 ACTIVE (835614390-835615175). The earlier single minute drops in SenseMon do not have any DQ flag nearby, nor are noted in the elog. I don't think this segment needs any other DQ flag.
8		838945244 - 838947647	11 +/- 2.6	Aug 07 2006 00:20:30 UTC	Operator's (J. Hanson) notes earlier problems with MC WFS, and about this segment: "0020 Locked SM; 0100 Took out of SM because of glitching; 0104 Valera turned down the WF1 gain; 0105 Back in SM". Mike Zucker's note about this time: "Two large peaks, at 31 and 34 Hz, appeared shortly after the IFO warmed up, degrading range and eventually overloading DARM. JH pulled out of science mode. Valera found it was WFS1 pitch oscillating and reduced both pitch and yaw gains; oscillation disappeared. " Many inspiral triggers generated at this noisy time, all but one 10s clusters are vetoed by ASC overflow DQ flag. I suggest a flag for the time between 838946880 and 838947647, due to the recognized problem in WFS1.
9		841184922 - 841188954	11 +/- 2.6	Sep 01 2006 22:28:28 UTC	Several segments in the plot are in the list with std>=1Mpc: the earlier one, starting at 21:04, is #61, with std=1.6 Mpc; the one highlighted here, starting at 22:28, is #9, with std=2.6 Mpc; the one that follows, starting at 23:49, is #35 with std=1.8 Mpc; the one ending the plot, starting Sep 02 02:21, is #130, with std=1.3 Mpc; the segment that follows the last in the plot (and the last before break due to daytime noise), starts Sep 02 8:04, is #208, and has std=1.0 Mpc. Microseismic noise is very large, the storm "Ernesto" was arriving to the Atlantic shore this day. Detector runs with "daytime power" even at night to preserve lock. The non stationary high noise is responsible for the scatter of the points, but the large range drops are more serious consequences, probably overflows. Dan Hoak says: "The spectrum is very nonstationary, and the excess noise is VERY broadband. It doesn't look like the typical upconversion - instead, the whole spectrum will breathe with a period close to that of the microseism. ASI and SPOB are very noisy.". SciMon Lindy Blackburn says, about early Sep 02 UTC: "held science mode through most of the night with inspiral range 12-14 Mpc. continued operating at low laser power due to high microseimic noise. instrument was relatively glitchy all night with kleineWelle rates showing good correlation with the microseimic activity. " Although the loudest inspiral clusters are vetoed by overflow flags, the rate of triggers during this time is significantly higher than usual. I suggest a tropical storm DQ flag for all segments between #2977 (starting at 841178132) and #2985 (ending at 841232742).
10		825700595 - 825705734	7.9 +/- 2.6	Mar 06 2006 17:16:21 UTC	Dan Hoak about this bad time: "We had a slowly worsening noise spectrum over a period of about thirty minutes today. Attached is a DARM spectrum during the period; the slope of the noise is close to 1/f. There were no overflows; I checked the OpLevs, QPDs, and the gold-plated conlog for bad news. The only hint of trouble was in the WFS; there was a lot of coherence between DARM and WFS1 pitch (the second page in attached document). The IFO lost lock before we could really dig our diagnostic teeth into the problem; when we returned to power-up the noise curve was back to normal." Same WFS1 problem as #8 on Aug 07? A DQ flag should be defined between 825703200 and 825705734.
11		820077107 - 820093611	9.3 +/- 2.5	Dec 31 2005 15:11:34 UTC	A time inadvertently running on AS5; there is a DQ flag covering this already: L1:AS_TRIGGER:v1 ACTIVE (820092340-820093611)
12		816750806 - 816752854	5.8 +/- 2.5	Nov 23 2005 03:13:13 UTC	The problem start with the previous segment, #63 in this list, starting Nov 22 23:37, with std=1.6 Mpc. Operator J. Hanson notes: "2329 Locked SM; 0052 Train; 0250 Broke we were having large glitches for the last 40 min or so; 0312 Locked SM; 0347 Broke the large gitches came back?" Ken Franzen scimon's notes describe the same problems, but also notes they were solved when a TCS script was run (the next segment is clean). There should be a DQ flag defined between 816742980 and 816752854.
13		841289009 - 841291321	13 +/- 2.4	Sep 03 2006 03:23:15 UTC	See comments on #2, 3. A DQ flag including this segment is suggested.
14		831569462 - 831572001	12 +/- 2.3	May 13 2006 15:30:48 UTC	Not clear what the problem is; operator (H. Overmier) notes "Large spiks in the STS-LVEA STS2_X_1-3Hz" as possible suspects for the loss of lock at the end of this segment (it is Saturday). There is also some wind, blamed for the previous lock loss. The next segment has a lower range because the power is lowered to allow for locking and low noise mode. Not obvious DQ flag needed.
15		828518267 - 828528802	9.5 +/- 2.3	Apr 08 2006 07:57:33 UTC	See comments on segment #1 (the one that ends this plot) , which include a suggested DQ flag applying to this segment.
16		841110269 - 841113985	12 +/- 2.2	Sep 01 2006 01:44:15 UTC	After a long hiatus due to 1-3 Hz daytime seismic noise and some trouble with a cold Faraday isolator, the detector started up at 22:16 (seg 2961), but it was in a "glitchy" state. Power was increased from 6W to 7W at 00:29, but it was set back to 6W for the segment highlighted here, due to glitchiness. It got better after Brian changed some WFS gain, at 5:00 UTC.The larger scatter in this segment compared to previous days is due to the increasing microseismic noise (the tropical storm Ernesto arrives a day later, see #9 above). I suggest a WFS DQ flag for segments 2961-2971.
17		825748577 - 825751666	9.6 +/- 2.2	Mar 07 2006 06:36:03 UTC	An earthquake that starts at ~6:00 ends seg#1155. While we wait for a true EQ flag, I suggest a preliminary EQ flag for GPS 825746414-825751666.
18		842050745 - 842054683	13 +/- 2.2	Sep 11 2006 22:58:51 UTC	Dan: "Glitches caused by a combination of high-power operations and elevated microseism. This was shortly after the August 06 commissioning break, when we were trying to push the envelope a bit." The first dip in range at ~19:00 (not in the highlighted segment) is a small earthquake (2.7 in Alaska), followed by a train. The second dip at ~22:00 is another earthquake (2.8 in Southern CA). At 22:24, after the EQ,the power is increased, and the highlighted segment L1-3082. After power is increased, the scatter in range is larger, and there are glitches. The segment that follows this one is #146, with a 1.2 Mpc std. Mike Z. (scimon): Since Doug went to night power about 7h ago the statistical FOM's have looked ratty. BurstMon pixel fraction went from 0.2 to 0.35 with fluctuations above .5, the online BNS search has numerous outliers above SNR=10, PulsarMon crabbytime went up a factor of two, etc. In addition we are seeing excursions of ASI_CORR to +/- 20,000 counts and occasional 30% dips in SPOB. [...]After an AS trigger at GPS 842074652 I asked Tom to roll back down to day power. Segment 3084 is at 5.6W." After the power is decreased, the scatter is smaller and most of the glitchiness disappeared. I suggest a DQ flag for segs L1-3082-3083, *and* an EQ flag for GPS 842034614-842038684 and 842045414-842048738.
19		816776927 - 816783836	7.9 +/- 2.2	Nov 23 2005 10:28:34 UTC	Dan: "Beginning-of-run glitches. They were noted, but not explained, in the elog.". I suggest a DQ flag for the whole segment, 816776927 - 816783836.
20		841305349 - 841316101	13 +/- 2.1	Sep 03 2006 07:55:35 UTC	Dan: "An earthquake in Panama reduced the sensitivity just before it activated the AS trigger." The previous segment ends with a dip due to a train, and the segment before that one (the clean one starting at t=-4) ends with a dip due to a large EQ; this segment is #86 in this list, with std=1.5 Mpc. The earlier glitchy times seen in the plot are described in #2(!) in this list. I suggest EQ flags for GPS 841313714-841316101 (end of this segment) and GPS 841295414-841296222 (for the earlier one). .
21		840201914 - 840205590	13 +/- 2.1	Aug 21 2006 13:25:00 UTC	Dan: "I think RBS saturated at the very end of the lock, making the IFO a little noisy for a few minutes. This was shortly after the new PMC was installed to increase the power into the IFO, and we hadn't yet adjusted our compensation loops." I suggest a (RBS?) DQ flag for GPS 840204314-840205590 (21 minutes at the end of the segment)
22		836831803 - 836834883	12 +/- 2.1	Jul 13 2006 13:16:29 UTC	Dan: "Segment ends due to a train. This was shortly after the SPOB PenTek failure. The ongoing efforts to debug that problem caused some minor trouble with WFS1, which led to elevated ASI during this segment." Segment L1-2445 ended suddenly with a lock loss on July 12 20:37, and there was a large offset in SPOB afterwards that made locking difficult. A work-around was found, but the problem was tracked down on July 18 to SPOB's Pentek. Segment L1-2507 is the first one without an SPOB offset. This particular segment has a problem with WFS and ASI, and they are associated with ASI-CORR overflows; I don't think there is enough evidence for another DQ flag. However... I think we should have a DQ flag for the whole time the detector was running with a mulfuncitoning Pentek, for segments L1-2446-2506.
23		825537372 - 825541189	9.6 +/- 2.1	Mar 04 2006 19:55:58 UTC	Dan: "From the scimon's report on this segment: "About 20 minutes into the segment, there were a couple of big glitches, and about 15 minutes later, it got really glitchy, same as yesterday; the segment ended with an AS trigger, and the next (short) segment ended with lock loss.... Most (but not all) the glitches produced LSC overflows in ASQ1-4, but not in ASI or ASI_CORR or ASC." ". I suggest a "glitchy for unknown reason" DQ flag for this segment.
24		837584169 - 837587647	14 +/- 2.1	Jul 22 2006 06:15:55 UTC	A train, already with DQ flag: 837587310 - 837587647.
25		841114112 - 841116223	12 +/- 2	Sep 01 2006 02:48:18 UTC	Dan: "A very short segment (2,111 seconds) with high microseism from TS Ernesto and one deep glitch.". This segment is included in a suggested "high power glitchy" DQ flag, see #16 above.
26		834292023 - 834295173	12 +/- 2	Jun 14 2006 03:46:49 UTC	Earthquake, 6.8, Aleutians. I suggest an EQ DQ flag, GPS 834294314-834295173
27		845327353 - 845330332	12 +/- 2	Oct 19 2006 21:08:59 UTC	Dan: "The glitches at the end of this short segment are due to an approaching train. Also, the IFO was warming up, and the microseism was elevated." The glitches in the warm-up time are not associated with ASI_CORR or SEVERE-LSC overflow flags, except for one. I suggest a glitchy warm up DQ flag for the first 20 min of this segment: 845327353-845328553
28		840530008 - 840540256	14 +/- 2	Aug 25 2006 08:33:14 UTC	Dan: "Segment ended by logging. There was no clear explanation for deep glitches before the seismic noise increased." There are 186 different ASI-CORR or SEVERE-LSC overflows in this segment; there are overflows in all the minutes after 11:15 (the segment ends at 11:24). It is not obvious we need another DQ flag...
29		825240304 - 825247839	9.4 +/- 1.9	Mar 01 2006 09:24:50 UTC	Dan: "No clear cause for glitches. The microseism was high, but the glitches began (and ended) spontaneously)". The preceding segment is #58 in this list. I suggest a "glitchy for unknown reason" for ~t=-3.5 to t=0.5 in this plot, or 6:00-10:00 UTC = GPS 825228014-825242414.
30		817207370 - 817212021	7 +/- 1.9	Nov 28 2005 10:02:37 UTC	Dan about #48 (the segment that follows this one): "An ugly segment ended by a train. There were ongoing problems with HEPI for ITMX (it turned out to be a broken PenTek)". I suggest a "glitchy for unknown reason" for both of these segments, or 817207370-817218064.
31		823328764 - 823333868	7.6 +/- 1.9	Feb 07 2006 06:25:50 UTC	Dan: "Microseism, noted in ops log". I suggest a "glitchy for unknown reason" for this segment.
32		826000845 - 826003434	7.5 +/- 1.8	Mar 10 2006 04:40:31 UTC	Dan: "Wind and microseism, same as #53 and 54". (#54 is the glitchy segment starting at 7:01). The glitchiness stopped when the useism noise went down. This FOM1 shows the segments following the ones in the plot. I suggest a "glitchy due to useism" for segments from L1-1185 (this one) up to L1-1197 (included), or GPS 826000845-826041719 .
33		828175034 - 828182027	9.6 +/- 1.8	Apr 04 2006 08:37:00 UTC	Dan: "Post-commissioning glitches, noted in ops log. Saturations in AS1.". I suggest a "glitchy for unknown reason" for this segment.
