Commissioning: 28 June 2010 UT

Summary

Network issues between OBS2 and NFS machine (home)
Seeing during the night has varied from 0.7" to 1.3".
A full set of Collimation data has been acquired.
We met problems to point to the Stone fields M and O where the target star was not found. It seems that there was a problem in the pointing model.
Concerning the Transformation data, we should extend the total exposure time per cube at 60sec. 30sec for a cube seems to fast to expect a collimation correction.

Preparations

Single frame names refer to: irtc.20100628.xxxxxx.fits

Cube names refer to: irtc.20100628_00xxx_cube.fit

Plan for the night: follow Doug's verification plan, in particular transformation data, collimation and pointing models.
