In nightwatch, z7 was pretty bad on nights in late November 2022. In some cases these have been flagged as bad for the night (e.g. 20221120) while on other nights they were not flagged as bad. Perhaps the impacted fibers are flagged as bad at the fiber-level rather than fully masked at the CCD level, or perhaps the nightwatch masks were out of date compared to what is used for offline processing, or perhaps we have a real problem and need updated masks.
As part of Jura QA, investigate these cases more closely.
