UT 20121022 AO#1 Wakeup

Observer:JCGuerra (LBTO), A.Puglisi remote(INAF)
Telescope Operator: David G.(LBTO)
Additional AO Support: JCGuerra (LBTO)
Telescope Support: Michael.K (LBTO)
Instrument Support: John M (LBTO)


  • Retro On. Some problem to find the RR brackets.

  • Startup of the DX size.

  • Telescope setup to work with the RR.

  • Alfio on line.

  • The W unit is set up without any problem to load the board setup.

  • Afio update all the routines that we have to work with the RR

  • Right spot center.

  • Test of close loop, autofocus of IRTC. Results shows a 66% in H with a non-optimized loop. A more detailed optimization is planned for tomorrow.

  • We had some error with the TCS subsystems, telemetry was lost and the the primary went to panic.

  • Handover 3:30


Start 08:00

  • Installation of the RR has been delayed till 9:30 due to the missing RR brackets. They were not in the usual storage location. This location is on the RR trolley.

  • The DX is power on the system came up without any problem.

  • W and telescope ready, the spot can not be seeing using the old hexapod position. The hexa_spiral procedure to acquire the spot is used. The procedure didn't work, is not installed properly in the DX side. Alfio is fixing this bug.

  • Spots found with hexapod position: 0.1,0,3.4,-303.9,-32,0. Hexapod position for the wide field of view in IRTC. Center the left spot. For the narrow filed of view the hexapod position are:
    Center the right spot. For the narrow filed of view the hexapod position are:

The pupil are digital shifted by 2 pixels and the rotaion offset changed by 1 degree. This is test with the Bin1, a more detailed check has to be done with the others bin. The new values are updated in teh w configuration files. Alfio is working on. (19:20)

The system close the loop with the a test configuration, there isn't any problem all the commands went through the system adn we could close the loop. The next item is to run the autofocus routine to improve the irtc image quality and to get some performance.

Center the left spot in the narrow field. Closing the loop and taken a few data, we can see the cross effect in the psf which is a high indicator that the spot is wrong. Data taken

19:20 Primary went in panic.

21:00 Lost telescope information and rip of the shell. Some subsystem has to be reinizilaze.

The left spot is not the right one. The right spot is moved to the cebnter of teh narrow field and test of close loop. The focus of the psf is adjusted running the autofocus procedure. With the focus and the AO optimal parmaters we close the loop and we run autogain. The autogain works without any problem.

With a non-optimized system we close the loop and some data are taken. We are having problems with the acquisition routine. The errors are reported to Alfio and we expected to fix the bugs. A results of a non-optimized psf is showed in the table and images below:
