Measure of astigmatism hysteresis

Note: the rms value is just indicative (rms from MirrorGUI positions), real value of astig will be found after reducing data.

At el=90deg the shell is set using flattening test_astig_00.sav.

Taken offset on MirrorGUI. The rms in the table is given from MirrorGUI: position rms wrt last taken offset

At 26deg AdSec was ripped because of 100% SkipFrame due to high force around +Y of central membrane. In order to avoid that we will stop to 30deg hereafter.

Go back to zenith. Remind that a first 90-28-90 loop has been done before next measurements (important because hysteresis)

Closed the loop at zenith, waiting for HP offloading and taken offset on MirrorGUI.

HP reference position: (x,y,z,Rx,Ry,Rz) = (0.0, 1.73, 3.95, -320, -38.0, 0.0)

Went down to 0deg and back to 90deg (to measure hysteresis loop in the 0-90 range. Remind that first travel to 0deg is not part of the stable loop in this range.
