LDG Commissioning: Performance Verification - 25 April 2010 UT

Night 7:

Observer: JHeidt (LBTO), PHibon (LBTO), JHill (LBTO), DMiller (Tucson)
Telescope Operator: JHill (LBTO)
Telescope Support: JUrban (LBTO)
Instrument Support: JMorris (LBTO)
Adaptive Secondary Operator: MXompero (LBTO)

Summary

Excellent, photometric night with mostly subarcsecond seeing conditions

No telescope failures

Took lots of preset, guiding, collimation and offset (dice5) data

Doug took a set of inverse field data remotely from Tucson

Preparations

Single frame names refer to: irtc.20100425.xxxxxx.fits

Cube names refer to: irtc.20100425_00xxx_cube.fit

Plan for the night: follow Dougs verification plan, in particular to test presets as well as collect dice-5 offsets.
