Commissioning Notes from 14th-15th June 2008 MST

Observers: D. Miller, A. Rakich (in Tucson).
OSA: David G.-H., J. M. Hill

Summary

It was another beautiful photometric night. The SX cell was completely out to lunch at the beginning of the night. It took us 5 hours of testing and swapping components before we learned that the problem was a bad network switch (or connection or something). See Issue #1450 for details. During that time, the DIMM guys got about an hour of work done. We finally got ready for observing a little after 1AM. The rest of the night was smooth sailing while we took data off-axis for measuring field aberrations. The new pointing and collimation models work well, although they need a shift in the X-direction to allow access to elevations below 40 degrees.
