The first one left a graph with some scattered points but I missed the Dark portion and didn't see if the values were around 0. The subsequent 2 gave similar graphs and the Dark values weren't around 0. MKIV COMMENT: Thu Aug 26 18:23:21 GMT 1999 Did an End Day to position the barrel, then reset the KCC to load new calibration software from David. Will try a Correct again.

For example, scans at 1920, 1928, and 1936 are darker than the scans in between.

COMMENT: Thu Aug 26 20:38:24 GMT 1999 Extended the dome slot. Thu Aug 26 20:42:55 GMT 1999 MKIV Start Patrol **MKIV PROBLEM**: Thu Aug 26 20:51:19 GMT 1999 After I started the Patrol the barrel moved but no data were taken, the barrel was stopped at a limit (around 278). I turned off the main mkIV power switch and the spar power strip and rotated the barrel to the other limit and turned it all back on. That turned out to be the limit where the barrel normally gets stuck so that didn't help. So I tried to point the barrel to near 0 degrees and repeated the sequence, then it rotated to get stuck at around 83 degrees (limit) again because I miscalculated. The thing to do is to point the barrel about 3/4 rotation from either limit to get it near 0 degrees so that it won't be driven to a limit when the KCC is reset. Thu Aug 26 21:04:09 GMT 1999 MKIV Start Patrol **MKIV PROBLEM**: Thu Aug 26 21:04:37 GMT 1999 OK, now Patrol is working correctly, I don't know what caused the initial problem where the barrel got stuck at the 270 degree limit. **** EVENT COMMENT ****: Thu Aug 26 21:35:22 GMT 1999 EPL taking off around PA=285.
