LgswSystem test w/ PYR

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:

Pupil	PMX	PMY
Blue	415	525
Yellow	275	375
Red	410	335

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...

We move back to DX system:

Also here the whole pupil oscillates...

LgswSystemSx AO calibration

Since the SX oscillation is always triggered by the top right pupil we check if it could be a problem due to mis-calibration... 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 push-pull (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...
