Power up issues

When we power up the SX LGSW the Pupil motor RED Y axis was not homing. We unmount the LGSW panel and we push by hand the stage and at this point the motor complete the home procedure (http://aowiki.arcetri.astro.it/ARGOSPublic/NSA12NotHoming#Procedure_to_recover_from_a_motor_stuck_in_the_fully_elongated_position). When we power up again the system the Pupil motor YELLOW Y axis was not homing. We repeat the procedure and then it works.

When we power up the LGSW from the arbitrator we got an error because the WFS camera controller gone in the "ErrorState". Here the log from the WFS camera controller

2017-03-02 16:35:56.635241214 ^[[31mERROR^[[0m WfsCamera sx-lgsw:9781.7fb7d2db9700 nobody WfsCameraDriver.cpp:71 void argos::wfs_camera::WfsCameraDriver::logAndThrowBasdaWfsCameraException(const std::string&) [^[[1m[State] 'StartPnCCD()' ignored. Cannot turn cooling on. Check statuses.^[[0m]

The PSU comminicating led in the GUI was red (Debug Statuses tab). we restart the kontron and start the pnCCD from the gui and it works.

Pockel cell transmission

In 5 hours the performance of the BLUE and the RED pockel cells decrease, in particular the right part of the BLUE goes from more the 100 (suppression factor) to 20.

SX AO calibration

With HBS on we see more vibration then without HBS.

HBS on, TN 20170302_190439: 1236nm of Tip/Tilt, all Open Loop

HBS off, TN 20170302_190814: 303nm of Tip/Tilt, all Open Loop

We work with HBS off.

The new modal History use the old modal amplitudes divide by a factor 2.

We test the new LGSW rec and we compare with an old one from October 2016. When we try to increase the gain the subaps on the top right start to oscillate. 0.8" disturbance.

We increase the flux and we try the old recs with 1.0" disturbance.

When I try to run the old modal history in Open Loop the ASM rip (stroke too big?).
