MDM Observatory 2.4m Telescope Observer's Report for 2002 Feb 07 Observer(s): Athey Institution(s): Michigan Instrument: CCDS Worked for 4 hours (part of the night) Conditions were Photometric most of the night. Problems were encountered, see the separate trouble report for details. Seeing and Weather: Beg: Clear, Winds Calm Mid: Clear, Winds Calm End: Clear, Winds Calm Observing Summary: IC computer for CCDS crashed. Maybe a disk problem?? - I replaced with spare IC computer. Gain for CCD with different with spare computer controler. Although data was okay with different gain, I spent a few hours diagnosing why my data looked different, not realizing the change in gain setting (thought it might be guider shadowing and other random thoughts). Various Ohio-State members were very helpful in fixing the IC computer crash. Thinking the solution was 5 minutes away (for 2 hours), I did not contact them concerning the gain setting. ------------------------------ Submitted on 2002 Feb 11 [7:23:01]
