      Description

      While validating the fix in DM-19265, it was noted that there are differences in the uber calibration results from both jointcal and meas_mosaic between recent weekly runs of the RC2 dataset. As the plots on DM-19265 show, there have been some subtle changes from w_2019_06-to-w_2019_10-to-w_2019_14. The differences are small (stdev of difference is at the sub mmag level), but it is still important that we understand where they originated. Since both algorithms are affected, the route cause must be something that effects both. A first guess would be something about how object selection is being done.
