Technical night

Summary

  • Bad observing conditions. The sky went from partlally cloudy to complete cloudy.
  • Close loop both sides in binocular preset.
  • Both sides close the loop.
  • Offset on Dx side were done. The stages moved with the flip in the AOS.
  • A first try to get a focus for Lucifer respect the FLAO_SX.
  • Steward building network down. Lost one hour.
  • After the network was stablished the two wfsarb went down. IT##5150.
  • It couldn't get it DIMM and SH measurements. Too couldy to keep the DIMM running.
  • Hand out about 5am, it was getting too cloudy and the sky was getting bright.

Issues:

  • Close loop with both sides and the configuraiton files for the Right and the Left are different in the step of Acquire Reference process. For DX side non filter is used and for SX a filter 850/40 is used. This ussed doen't allow to pick up a star that it was clearly visisble and saturated in the CCD47.
  • Close loop in a variable sky is too weak. A better control of the skip frames and a pause of the loop could be implemented. something to think and improve.
  • Observed that during close loop in binocular mode, the tip/tilt start to oscillate periodically in about 0.6 seconds, from John Hill plots of the SX and DX thin shell offload we can see a periodic oscillation. Issue track open #5154.
  • two message deamon died after the network in Steward went down.

WFS_DX and WFS_SX

WFS_DX Power on. Failed. Error message: "2014-04-18 03:43:35.579434 Timeout waiting for picctrl.R.Status -code:-5--1 TIMEOUT ERROR.".

A second try to power on went succesfull.

WFS_SX Power on. OK

Authorize both sides: Active preset on the Right side and ACE preset to the left side using the binocular preset.

The sky conditions started to get cloudy
