We start in the afternoon testing in remote the PC #5 suppression on

Cal Unit activity: we center the yellow pupil:
We take snapshots closing the loop on ARGOS:

We switch on FLAO, we optimize the PSF on CCD47. Loaded
FLAO pupils positions: 20130916_000000
We build mixed FLAO and ARGOS reconstructors, using FLAO bin 2 REC 20130916_221257
REC ARGOS yellow 150 modes + FLAO TT bin2: 20140516_014823
REC FLAO bin 2 150 modes: 20140516_030138
We try to acquire ARGOS Slope Offset when the FLAO loop is closed (150 modes):
ARGOS slope offset: 20140516_141000
We try to close the ARGOS loop using slopes offset but it diverges. We try to filter the ARGOS slopes null on the yellow reconstructor at 150 modes. They seems not fine. We acquire new ones:
ARGOS slope offset: 20140516_141400
22:14 Switch to on-sky activity, we start pointing at Zenith.
22:43 lasers are finally on-sky

check for LGS drift, it is small over 5min... |
We point at a star at EL 82deg, we collimate the telescope, seeing about 1.1":
We try to close the TT loop on ARGOS but it moves the LGS away from the LGSW

LAN focus at -45k and ToF at 83us |
We point at a star at EL 73deg, recollimate, and we check the PSF on CCD47. Start tacking. Flexure compensation is on.
