Subapertures redefinition

Yesterday the loop was diverging for high order gain > 0.1. Most of the time the failure was triggered by the central actuators around the central obstruction. We try to redefine aq proper subaperture set avoiding the certer cross subapertures around the obstruction.

On Yellow we need to remove: 251, 265, 266, 267, 281

On Blue we need to remove: 74, 88, 89, 90, 104

On Red we need to remove: 428, 442, 443, 444, 458

Since we want to add 2 edge subapertures (527, 528) on the Red one we try to start from scratch.

We need also to remove the top row of the Blue pupil.

Subap CoG: 20150226_233800 -> BAD top row in Blue pupil is WRONG!

Subap TCoG48: 20150226_234900 -> BAD top row in Blue pupil is WRONG!

Then we try to record another IM but instead of subtracting the TT component from the higher order modes we close the AO loop on the LGSW using a sensible gain on the TT terms:

RECs test

We try to close the loop using a disturb = 1.2". We try to make ASM oscillates to check the maximum gain applicable (g=0.9 in case of TT RM). We compare the TT RM and TT g=0.3 RECs.

BUG in REC generation & new RECs

It is caused by indexing problems, discovered multiplying the REC by the IM (TT removed). Figures below show the result of the matrices multiplication in case of the old REC (20141202_125200) and of the newly generated REC (20150227_023600):

Hip 67995

3:00: after having optimized the LGS spots the loop is more stable... Seeing is about 1.2". QC is running at 1kHz, 1300 counts. TS is on, PYR BIN4, 1kHz, 70 counts/subap, m=12.6, FW1=50-50.

After the gain is stable to 0.6,0.4,0.2 we take LUCI images range from 0008 to 0017 are in H band (3s), images in the range 0019 - 0028 are in FeII band (3s).

We close the TT loop on a bright star, the pupil mirror starts to oscillate in different directions, we record the proper LGSW signalswith snapshots. We have also a set of LUCI images 0029- 0038 when just the TT loop was closed (field stabilization).
