The information that is plotted in each figure (movie) is detailed below.
then selected a "rainbow" color scheme of the form,
On the right-hand-side of each frame we have plotted amplitude versus radius in the equatorial plane of the star. Although this plot does not (yet) contain a vertical label, you can still get a pretty good idea of what is going on by realizing that the vertical scale goes from amplitude = -7 (bottom) to amplitude = +0.5 (top).
The integer at the top of each frame identifies the frame number. Frame 1000 corresponds to the initial model; thereafter, successive frames are separated by 1/600th of a rotation period.
