LgswUnitSx test with FLAO as TT sensor
The system is setup for FLAO BIN2 using parameters of yesterday, the light is well in place.
BOARD SETUP: 12 Dec 15 - ARGOS_BIN2
Center of FLAO
FoV is at stages position: -77.5; -49.1mm. To pickup the white light source when controlling the system with the AARB an offset of +5.5; +2.4mm must be sent when lauching.
CalUnit white light source is switched on automatically by the AARB, when fully opened it is equivalent to a magnitude 9.0. This value must be set in the AARB GUI before launching.
TT loop closed on PYR BIN2; 150modes on LGSW; no disturb; JCL:

10:30: the
BCU continues to stack, we fear a possible under-powering problem. We try to run the
BCU at 500Hz but the problem persists...
We find out that when the FLAO slopes are enabled and the jitter loop is closed, the piezos start to oscillate. It seems that we are writing the FLAO slopes in the wrong
BCU memory address...
11:15: we switch to check
LgswUnitSx calibrations: system setup at 500Hz.
TCoG48 subaps are loaded (20151211_181800).
We close the loop on LGSW only and we acquire the best flat for the sensor.

We are running at 500Hz and LB complains, so we set 610Hz and we repeat the IM:
On both on them the red pupil shows ear: we discover that the jitter loop was closed.

PBL: we find that the argos.lgsw.controllergetFrameRateFromControllerInHz is oscillating between 400 and 800Hz while
BCU reads just 570Hz...
we try to generate a modal history having 10 steps up and 10 steps down per mode (that's actually no push pull) to wash out the frame rate oscillation.
Last one seems the best one so far, but blue pupil is quite noisy... We try to offset the hexapod pointing by [0.0; 0.2]arcsec.
We change again the hexapod pointing by [0.0; -0.4]arcsec.

w/o TT removal |
We try again to acquire an IM with push-pull: 3 steps up and 3 down:
We try to disable external clock and to run on the LGSW internal one to see if the frame rate stops to oscillate.
We fear a problem with OVS.
14:30: we also fear that maybe the TT amplitudes are too small, so we use the original DX modal amplitudes to biuld the
modal history: 20151212_213400_150modes.
We build a combo rec on last push-pull IM and also on the 10 steps ones:
We test these Combo recs, w/o disturb they oscillates between 0.4 and 0.5. We load 1.0" disturb:

Best Z stage position for N30 camera is 52mm.
We combine now LGSW recs with FLAO ones:
