March 6, 2008: finished defining segments and recommendations.
March 31, 2008: Included intersections with science times, including
injection times and interval durations.
I calculated the median SenseMon range in each H2 science segment in
S5, and the standard deviation of each segment longer than 2048
seconds. The standard deviation is a rough measure of "glitchiness",
with the histogram showing a long tail. I ranked the segments according
to their standard deviation, and investigated reasons for the large
stand rd deviation reading the elog, especially entries by operators
and scimons. I suggest DQ flags for the segments investigated and
sometimes
other times, arising from the investigations.

Times in science segs (gps start, gps stop, H2 science seg#).
(The last column generated by segwizard is not the duration, it is copied from original science segments file).
The file above does not include injection times.

called "Valentine's noise" afterwards. Previous segment is #103. Flag the time in the three science segments shown in the plot (end of H2-2247, H2-2248, and short H2-2249). H2 SICK Flag 855474336-855506700 |

magnitude 7.2 earthquake off Java that knocked
both IFOs down for most of 2 hours. Surprisingly, Mark was able to
squeeze a few minutes of H1-H2 coincidence operation during some of the

H2-325 on Jan 20 15:38. However, some segments near the end are so glitchy that the analysis of the segments is probably biased.

|
8 | 844031308-844035240 | 6.2+/-1.4 | Oct 04 2006 21:08:14 UTC | Lots of ASI_CORR overflows for the

15 | 857679613-857682040 | 6.8+/-1.2 | Mar 11 2007 20:19:59 UTC | Stefan Ballmer follows
up H1H2 coincident noisy times (!), suspected H2 1.2 Hz stack mode
and unknown coupling into H1, between 20:30-20:45 UTC. There are also wind flags near this time, maybe it was just wind ringing up H2 stack and H1 too, but wind flags are only on for few seconds. XXX Elog suggests H2 problem was seen earlier too - should be followed up. Also, there's a mention of another H1H2 "event", but no timing info. (Segment H2-2380 with a noisy end, coincident with noisy H1, is Rank#119, but it has wind flags explaining the noise.) Also from elog, ETM problems sometimes affecting DARM are identified, we should probably follow up with a flag. Suggest H2Stack flag 857680214-857681114 |

16 | 850276994-850282744 | 6.7+/-1.2 | Dec 16 2006 04:03:00 UTC | H1 lockloss, lockgain (flagged)

19 | 828362372-828364470 | 6.2+/-1.1 | Apr 06 2006 12:39:18 UTC | Only a couple of drops, probably

21 | 866338873-866353395 | 6.6+/-1.1 | Jun 20 2007 01:40:59 UTC | A segment in a very bad month: serious drop in range seen
near day 600 in S5 plot. Problem
starts on June 12 (H2-2814, Rank#120), although
at the time it was referred as an old problem: "On the last hour the
broad noise was present". The range becomes higher and stable on July
11 20:00 UTC, after an RM suspension problem was fixed.
H2-2937 had 7Mpc and only seismic glitches at the beginning, later
segments were OK. Keita says that the RM problem was only one of
probably two different problems. Some segments in this month are glitchy, others simply have low range, but I suggest we use a long H2BADMONTH flag between June 12 12:00 UTC and July 11 20:00 UTC, and use "H2SICK" flags for glitchy times, like the end of this segment. A different page shows all the segments in this bad month, with suggested flags. |
