Hello members and Roboscopes team,
I think we need new flats again. I looked at the data of NGC7497 and calibrated it with the December flats. After stacking, an artifact remains in the lower left, which looks like dust to me. I have marked it red for clarity. I have the problem in APP as well as in PI.
Regards
Darius

I think this is actually due to mixed of data between Nov 2021 and Jan 2022.
Based on my tests, the Dec flats can effectively calibrate most of the Jan data, however, neither Oct nor Dec can effectively calibrate the Nov data.
I don't think we can do much on the Nov data, the only way is to resubmit a job.
