UT 2020 Jan 07 --- AGW3@RFBG in parallel to TSIP science in 2nd half

Summary

I (JMH) flipped all the 5 variables individually (WFS_pupil_shift_x,y and WFS_pupil_dir_x,y) that I suggested before, and none of them fix the pupil shift problem. It is still the case that GCS has the shift wrong by 1 lenslet row and 1 column for a guide star at x=-97,y=502. This guide star is OK for the rest of the night, and I'm heading home to think about what else can rotate the direction of the shift.

This was fixed for the start of the following half night. See the analysis below.

Details

Jenny and Shane doing TSIP observing with LUCI/LUCI. This AGW3@RFBG work happening more or less in parallel.

08:36 UT native 0,569 mm (maybe pupil is 1 row low, GCS and IDL agree on the shift)

08:48 UT native 0,612.5 mm on-axis (maybe pupil is 1 row low)

08:52 UT native -97.5,502.3 mm (SFP +97.58,+108.29) (now IDL and GCS don't agree on the shift)

08:54 UT WFS_pupil_shift_x from +1 to -1 (made x-shift worse, undo)

08:56 UT WFS_pupil_shift_y from -1 to +1 (made y-shift worse, undo)

Clear Active Optics on DX M1 and M2

09:04 UT WFS_pupil_dir_x from +1 to -1 (worse, undo)

09:06 UT WFS_pupil_dir_y from -1 to +1 (worse, undo)

09:08 UT WFS_r_to_pupil_shift from +0.19 to -0.19 (worse, undo)

GCS pupil cutout remains 1 row low and 1 row right is if the shift is rotated

09:36 UT Loaded new DX AdSec flat - maybe a small improvement

09:47 UT Set PSF M1 ACTIVE OPTICS gains to zero for Z9 and Z10. This made the LUCI2 images look better.

Numerical results from idl.log

From IDL idl.log file in obs2:/tmp/21852/

Note that WFS_pupil_shift_y at 09:56 makes the GCS amplitudes agrees with IDL but with opposite sign. If we then ALSO change WFS_pupil_dir_x AND WFS_pupil_dir_y then both amplitudes and signs should be correct. This solution was applied for the start of the following second half night.
