All but one caused 'Use Cleaning Tape' LED to go on upon loading. Loaded grey Fuji tape between each white tape test and each time 'Use Cleaning Tape' LED would go out without any cleaning cycle. Set all the white tapes except for the one that did not trigger the LED aside until this problem is resolved. Use only the grey pile for now.

Last correct probably did that somehow. Couldn't tell if noisy dark moved with swaps at various places because of gain differences in ch0 and ch1.

I did find a curious situation where the image discontinuity dwas not affected by system/card/chip swaps, but I could move the discontinuity inward, until it overshot to the outer rim again, by cycling analog power, typing allfresh on akamai, and running a correction. I left correctors with the discontinuity at the far outer edge of the chan 0 image. The discontinuity is a function of the gain correct function, I think.

I was repeating the chinese fire drill he did when they were out here--didn't remember.

Repeating Correct with flat table. If the drop does not move, I think David's explanation is correct, just have to find a good corrector table Tue Apr 28 22:41:50 GMT 1998 MKIII End Correct Tue Apr 28 22:43:33 GMT 1998 MKIII Start Correct Tue Apr 28 22:49:37 GMT 1998 MKIII End Correct Tue Apr 28 22:51:39 GMT 1998 MKIII Start Correct COMMENT: Tue Apr 28 22:54:06 GMT 1998 Tapes: Recycling MKIII tape all tests PICS: P01180 CHIP: C00570 LOWL: L00511 Tue Apr 28 22:57:44 GMT 1998 MKIII End Correct COMMENT: Tue Apr 28 22:58:13 GMT 1998 Hooray! I moved cortab0.199709261852 into cortab0.current (copied, actually), then ran a regular correct (did not request flat corrector table--that one had a drop approximately 1/3 of way from outer edge). This time I got a decent gain correct ramp. I will leave corrector this way.
