Commissioning: 4 July 2010 UT

Observer: Pascale H (LBTO), SW Group (Tucson), Doug M (Tucson)
Telescope Operator: Steve A (LBTO)
Telescope Support: (LBTO)
Instrument Support: Tim S (LBTO)
Adaptive Secondary Operator: Pascale H (LBTO), Runa B (Firenze)

Summary

Pointing tests realized for the SW group at the beginning of the night.
Second half of the night : pointing model data.
Problem for obtaining a good collimation and a good focus.
A lot of Astigmatism present in the pointing model cube.
The stars chosen for the pointing model are systematically too bright for the WFS.
(SATURATED means the star in the data cube is saturated. )

TCS test with Binocular Mode with the SW group in Tucson

02:38 in communication with the SW group in Tucson.
The TCS has been shut down and it is getting restarted.
02:52 The Shell is set as flat. The look-up table is still disabled.

03:13 pointto ACT0173 Tel="ACQUIRE" gs= 0 PA=0 PAM-
Failed. We need to used another version of the IRAF/IRTC software as we are in Binocular mode.
Steve is calling Dave.

03:23 pointto ACT0174 Tel="ACQUIRE" gs= 0 PA=0 PAM-
The pointings are failing due to a problem with the Binocular mode. (the left side refuse to move with the right side...)

Steve is doing a ptspiral. ptspiral is now ptspiral_right.
