*Anom-R6: Processes that are sending entries to the Survey Table identify anomalies that would invalidate an image, including any of the conditions in Anom-R5, plus: meteor/airplane trails that ruin substantial parts of images.*
If whole frames are unusable for one of the reasons in [[Anom-R5]], they might have to be re-observed. The concern for Anom-R6 is for airplane or very-bright-meteor trails that are so bright that they render a good fraction of the exposure unusable. In which case the Survey Table needs to reflect the fact that the exposure needs to be re-taken, so there is an operational issue.
[[Anom-R5]] must be run. In addition: raw science image of science mode exposure time + calibration images of that night. A piece of code that can add bright trails which invalidate a large fraction of the image.
Check DB output of Image Health / Quick Reduce for the faulty images from [[Anom-R5]].
Check DB output of Image Health / Quick Reduce for the bright trail image.
Secondary procedure: Check images with actual satellite trails for what they look like in the DESDM processed frames (should be masked).
If flags are raised for a trail that destroys 10% of a chip and all faulty frames from [[Anom-R5]], test is passed.
If masking of tracks is incorrect, secondary test is failed.
If flags are not raised, either IH/QR must be tuned or DESDM must contain code to detect this and report it to the DB.
If masking is incorrect, DESDM codes need to be iterated.
