Ran Correct. May be corrupted because the corrector values were scrambled at the beginning of Correct because of the analog system power down. Not sure if that affects the correct process. Resulting Patrol data is streaked. Will try Correct again.

Doing this because Cal-15 images the problem better than Corona. MKIII COMMENT: Mon Apr 27 21:14:24 GMT 1998 Restored system to original hardware state--just found out Alice is fiddling with the scaling--which may have been causing the 'noise' I was seeing which began this Chinese fire drill. I will wait until Alice finishes her work before resuming this drill. Mon Apr 27 21:18:20 GMT 1998 MKIII Start Patrol MKIII COMMENT: Mon Apr 27 21:27:46 GMT 1998 According to Alice, she didn't start fiddling until well after I began working on this problem--so it's probably not her.

Nothing was made bad by her fiddling--it was actually improved if you ignore the bigger problem.
