That is probably when it just woke up. Cleaning LEDs were blinking so I cleaned drive #0, moved L00469 from drive #1 to drive #0, installed L00470 in drive #1. At Steve's request I changed the heater setpoint outside from 23 C to 25 C, and I will check the cable and board seatings to the control computer in an attempt to track down the CCD bias problem that has been affecting us since March 1996 but which has been detected only recently. For some reason the bias or dark level of the CCD camera changes about 1 hour after the instrument starts and changes back at the end of the day, those are Steve's words.
