DPMON COMMENT: Sat Jun 29 17:12:49 GMT 1996 I can still see the streaks and dots that look like dust at a focus on the Display window image, but it is not evident in the Camera window image. Could it be coming from the way the image is handled in the Display window? Are those images calibrated whereas the Camera window images are raw? DPMON COMMENT: Sat Jun 29 17:27:35 GMT 1996 Reading the CHIP manual reveals that for the CHIP (and dPMon?) the raw exposures are added and dark and gain corrections are made to them before they are displayed in the Display window. So there is probably something wrong with the dark or gain information being used, does this information change from daya to day? I'll see if the streak and dots change sometime today.

There is a bright area near the top of the image that looks like a light leak or an optical wheel may not have made it completely to a position. Checking the Daystar and filter wheel and occulting wheel in the dome shows no problems. ater Sat Jun 29 20:08:06 GMT 1996 CHIP End Water Sat Jun 29 20:14:28 GMT 1996 dPMon End Patrol Sat Jun 29 20:30:28 GMT 1996 dPMon Start Patrol DPMON COMMENT: Sat Jun 29 20:32:35 GMT 1996 Paused program for a while to check disk images for the problem mentioned before, but can't find a good way to get single disk images on the display window.
