18:00: we start setting up the system: we acquire new Dark: 20141129_020106

18:18: we point Hip117974 on FLAO, bin2, 400Hz, 70phot/subap

We start laser propagation but the beacons are really out, we acquire with MATS. On top of this we have problems with collimation.

!8:40: FLAO at 550Hz, ARGOS at 510Hz.

PBL with ASM: shell panic probabli due to AARB restart

LAN focus at -75k steps, LAS ToF at 85us.

20:18: we move the periscope to better recenter the 3 LGS on LGSW FoV

We define a new PatCam target: 20141130_013400

PatCam X Y
Blue 178 125
Yellow 181 121
Red 180 131

After that we acquire a new PatCam to Periscope IM and REC: 20141129_050500

We set as new laser acquisition target: 20141129_052400

21:35: we preapare the REC for a single LGS having TCoG48 slope computation algorithm, we use the Yellow LGS:

COMB. REC TAG REC LGSW FLAO REC COMB. REC
Yellow TCoG48 only 20141129_054100 - 20141129_054200
Yellow TCoG48 BIN2 20141129_054100 20130916_221257 20141129_054300

22:38: we recollimate (it takes a while!)

we close the loop just on FLAO, 150 modes, OK

we close on ARGOS + FLAO, 500Hz

20141129_071327 G=0.2,0.1,0.1
20141129_071633 G=0.3,0.2,0.2

We acquire the IM between Periscope and LGSW slopes ad we close the loop on it to prevent the LGS drift

Periscope LGSW TT REC: 20141129_072736

TN Notes
20141129_073330 G=0.3,0.2,0.2
20141129_073446

23:39: we put a star on FLAO and we try to close the TT loop on that

TN Notes
20141129_075351 G=0.5,0.4,0.3

we set the Z stage on FLAO to 27mm, the best position for LUCI (when the telescope is collimated we have the stage at 42mm instead).

We optimize the astigmatism corrector angle: 800 steps

We optimize the ToF: 85us are fine for Z stage at 42mm, we go with the stage at 27mm and we measure 10um of focus on the TS. We close the TS, the focus term is offloaded on the LGSW signals. We reoptimize the ToF: 85.8us.
