UT 20120207 - AO2 commissioning @ LBBG

Observer: KBoutsia, JHill (Tucson), JCarlos (LBTO)
Telescope Operator: DHuerta (LBTO)
Additional AO Support: SEsposito, EPinna, APuglisi, MXompero
Telescope Support: JUrban(LBTO)
Instrument Support: DOfficer (LBTO)

Summary

Late start because of clouds. We start opening dome at around 3:00UT.
Sky conditions poor; cloudy Pisces ND holder plate was aligned, remains on sky test with the ND filter

Note: There were some parallel/parasitic measurements with AO2 during the previous night Commissioning.Com20120206 .

Prest in ACE mode using the iif. The preset end ok, but the command didn't go to the TCS and the AO system. Doug M was called, probably is na error in IDL that try to connect to the IRTC, authorization.

The close loop was done using the AOS.

The system works well closing the loop giving a performance of about between 80%-90%

preset AO470 mag.7

Close the loop using the AOS.

The iif didn't work, the preset was received ok in the telescope , but there was a difference in the pointing between a poiting used by the TO and the pointing used with the iif. pointing with the TO (mode active), the reference star is in the CCD47 fov, instead if the preset is sent by the iif the star moves away from the CCD47 fov

Failure from the WFS side.

The loop is close from the WFS side.

ND holder plate align and left in place. On hold till we can align on sky or using the retro-relector.

The pinhole is aligned in teh center of Pisces image. The pinhole was centered first in the ND holder and moving the plate we could center the pinhole in the center of :Pisces image. * Imae: pisces.20120207.0069,70,71.fits. The image below shows the center of the pinhole. Pisces.20120207.0071.fits
