10:00: spots are within the LGSW
FoV, we have strong coma: we must flatten the shell. We close the loop on LGSW only and then we save a
shell flat: 20150630_ARGOS_LGSW.sav.

While the loop was closed on LGSW we take the best focus position on FLAO nulling the Truth sensing modes (FW1 on 50-50). Current positions are best for matching the 3
CalUnit spots within the 3 LGSW
FoV. We must find the best position for each individual
FoV:

The offset of the best
FoV center on the
BlueChannel is [0.15; -0.3] wrt the common center position = [-69.75; 47.9]
We set the stages there and then we move by +/-3.0mm from this position to get the spot position on the
PatCam.
Central pixel for the Blue PatCam is [180; 128]
We are also able to evaluate the
patrol camera plate scale: 6mm = 10'' = 48px (@ bin4) =
0.208''/px
Comparing this value with the old one (taken by eye) we have an offset of [0.6; 0.4]''.
Yellow offset wrt P0 = [-0.12; -0.45] => Yellow center = [-70.0; -48.0]
Red offset wrt P0 = [-0.8; 0.9] => Red center = [-70.7; -46.7]

Red seems quite out wrt the old position... we try again the scan starting from [-70.7; -46.7] and we take the stage positions at which the Red pupil has 0 flux.

Best
FoV Center for
RedChannel @ [-70.55; -47.0]
So new central pixel for the Red PatCam is [182; 126]
The 3 hot pixel positions have been saved into a new
Patrol camera target: 20150701_075500.fits.
Piezo initial position
We go to the center of the Red
FoV moving stages to [-70.7; -47.0]. Then we close the piezo loop and we take the mirror offset. We repeat the procedure for all the 3 channels:
These new piezo positions have been saved into a new
jitter initial position: 2015701_080100.fits.
LUCI2 best focus (N30 and N3.75)
11:00: we check the best focus on LUCI using N30 camera and closing the loop on FLAO.
BIN1: REC= 20150125_161348, because of dome light we cannot use BIN1
BIN2: REC= 20130916_221257, we take images on N30 while sweeping the Z stage.
We check the old N30 images taken during the FLAO+LUCI commissioning that were getting almost 70% SR with BIN1: Z stage was at 55mm (bwt LUCI was removed and reinstalled in the meanwhile), rotator angle was 210deg. Reference file:
luci2.20150404.0173.fits.
So we move the LUCI rotator to 210deg, we set the stage to 55mm and we optimize the FLAO gains: we have something really similar... We sweep between 50 and 60 and we find the
best focus N30 = 56.5mm. We take LUCI images at each step in the end we take 20 dark frames.
We move to N3.75 and we find that the
best focus N3.75 = 60mm
New Rec test
15:45: we try the new TM reconstructors:
