8:30: start of calibration unit activity, spots are already in LGSW

HEXA	X	Y	Z	Rx	Ry
	-5.02	-7.27	4.38	-365	135

We close the loop without disturb, using TCoG48, and we acquire the new position of the Hexapod once the 3 LGS are centered on the FoV minimizing the tilt on the 3 subaps patterns:

DoF	X	Y	Z	Rx	Ry
HEXA	-5.02	-7.27	4.33	-363	139
TS offload	0.0	0.0	-0.05	1.64	4.10

We switch on the on-axis surce, lamp steps @ 55

We load the pupil target 20141126_183730 and we close the pupil loop.

TN	Notes
20141127_170653
20141127_170734

We set the jitter loop gain to 0.01 and we close

Pupil	PI X	PI Y
Blue	-0.83	2.30
Yellow	-1.20	-0.85
Red	2.40	-1.80

TN	Notes
20141127_173430	Jitter is drifting because the TT loop is also closed on LGSW
20141127_173613

PBL with DSM: when we send the closeAO command the shell RIPs because of housekeeping errors... Probably related to ARGOS Arbitrator connection through ICE interface.

We build a mixed FLAO - ARGOS reconstructor.

Combined reconstructor with FLAO BIN2

COMB REC TAG	ARGOS REC	FLAO REC	COMB REC
TCoG48 + bin2	20141126_215200	20130916_221257	20141127_180600

Combined RECs test

We close the loop with TCoG48 bin2 REC, PCL, JOL, FLAO is running at 200Hz

We activate the TS loop, REC for TS is Rec_20130916_221257_argos.

TN	Notes
20141127_192528	G=0.5,0.4,0.3, stage Z = 36mm
20141127_192921	stage Z = 33mm, modulation = 5V
20141127_193142	modulation = 4V

We try to stabilize the PSF on CCD47, we have to rise the TT gain up to 20!

TN	Notes
20141127_195627	G=20.0,0.4,0.3

PBL with DSM: having restarted the Arbitrator and closing again the AO loop the shell RIPs again for housekeeping error...

PBL with BCU it stacks when framerate is > 500Hz...

Pupil	PI X	PI Y
Blue	-1.61	0.41
Yellow	-0.63	-2.53
Red	-1.22	-2.20

Now we move the FLAO Z stage @ 42mm and we close the AO loop just on FLAO. Since the FLAO slopes are still passing through the ARGOS BCU also this loop is running at 500Hz.

We close the TT loop on FLAO bin4 @ 250Hz with TS and ARGOS correcting 150 modes. Stage Z is at 28.5mm.

20141127_232118	G=6.0.4,0.4, Gj=0.5

We ramp up the jitter gain up to 0.7 and then we brake everything...

We restart with PCL and JCL, AO loop is open disturb = 1.6":

Rotation of PatCams interaction matrices

Since the 3 Patrol Cameras have been dismounted after the August LGSW removal we have measured the new orientation:

PatCam	Mar	Nov	Delta
Blue	0	184	+184
Yellow	-150	-158	-8
Red	160	170	+10

So we restored the March reconstructors for LM1-PatCam and periscope-PatCam algorithms and we applied a rotation:

Algo	Mar	Nov (cwise)	Nov (ccwise)
LM1	20140323_033220	20141128_021900	20141128_ 025000
Per	20140322_072532	20141128_022000	20141128_025100
