DPMON COMMENT: Fri Oct 7 19:00:55 GMT 1994 EPL at PA=260, RV=1.1 Fri Oct 7 19:02:07 GMT 1994: Calibration LOW-L COMMENT: Fri Oct 7 19:16:36 GMT 1994 removed L00112 from drive#0 and installed L00114. MKIII COMMENT: Fri Oct 7 19:32:50 GMT 1994 Slight depletion noticed at sight of the last EPL (PA=260). Fri Oct 7 20:02:03 GMT 1994: Calibration DPMON COMMENT: Fri Oct 7 20:39:55 GMT 1994 Pausing to extend dome slot. Switched to optimum disk image setup.

Fri Oct 7 21:12:52 GMT 1994: Patrol Start DPMON COMMENT: Fri Oct 7 21:12:56 GMT 1994 Started Patrol with disk exposure set high (70 ms) to see where bright spot is. DPMON COMMENT: Fri Oct 7 21:21:40 GMT 1994 Paused for Daystar test.

I found the reason for the change in Daystar vignetting throughout the day. As we correct for occulting by moving the O1, the bright spot moves across the disk image, probably due to the slight tilt of the O1 as the telescope moves about the gimbal. I tried using the occulting corrections while taking disk images manually and found the same trend that we see during the day. Therefore we have to set the Daystar tilt so that the disk images aren't vignetted for a particular time of day, probably the morning when we get the best data.
