Cirrus is so thin, intensity should not be affected. The coronal scan two before the cal looked OK. The one just before the cal was bad. The one between cal0 and cal15 was bad.

Alos Gif display shows bad rays geocentric north at a location where the corona is faint. The raw data show no such bad rays at that location! I think the calibration sees small or slightly negative Q and reverses the sign thereby causing the bad rays.
