LgswSystemSx and LgswSystemDx resume

8:00: startup DX we have several problems:

1. error camera: PSU is not communicating, we reboot the Kontron and it is solved
2. pulse generator: is offline, we power cycle the whole rack and it is solved

9:30: SX camera has been pumped

10:00: loop closed on DX system, no disturb:

Experimental RECs test

Informations are available here: http://aowiki.arcetri.astro.it/ARGOSPublic/SXAoLoopSinusoudalDisturbance

12:00: we test the experimental RECs on SX system. We start from LO and TT removal. LGSW only REC: 20170421_075500

Here we have a problem because there is no TT correction, we must do the test with the PYR combo REC, the LGWS only is useless...

So we go back to October '16 REC. We do the test w/ 1" disturb:

We have a Shell RIP

Sinusoidal disturb test

13:10: SX shell is back, we start from the SX system

A light in the dome was ON and some subaps have an halo. The slopes show a little disturbance in these subaps but is not affecting to much.

In the SX system the ratio btw coma and astismatism is about 45%, in the DX system it is 78%. Spherical vs focus terms are 45% and 68% respectively.

We try the same simultaneous CL test w/o disturb:

Also here the ration btw coma and astigmatism is 45% in the SX system and 75% in the DX one. The spherical vs focus instead are 40% and 45% respectively...

We try to reposition the pupil motors on the DX side:

Pupil	PMX	PMY
Blue	415	550
Yellow	275	350
Red	410	320

We test again the DX system w/o disturb:

In this case the coma vs astigmatism ratio is 78% and the spherical vs focus is 40%.
