9:00: we startup both systems but we first try to close a loop w/ PYR on the
DX system.
We try to reoptimize the pupil motors positions while in CL:
Then we load
0.8" disturb:
Then we move to
SX system
No disturb:
The system oscillation is triggered by the top right edge of the pupil.
We try w/ LGSW only:
The astigmatism oscillates more w/ PYR than LGSW only...
We try a loop w/ PYR Bin4 only:

With PYR the whole pupil is oscillating, not just an edge...

Also here the whole pupil oscillates...
Since the SX oscillation is always triggered by the top right pupil we check if it could be a problem due to miscalibration... We acquire new IMs with 0.05, 0.10 and 0.20 modal amplitudes. Just the latter case is decreasing the blue pupil illumination when performing pushpull (saturation?).
 COMBO REC TCoG48 only: 20170429_235900 has been created w/ 0.05 modal amplitude
 COMBO REC TCoG48 only: 20170430_001401 has been created w/ 0.20 modal amplitude

Also in these cases the oscillation is triggered by the top right edge of the pupil...
