      Description

      Zogy suffers if there is inaccurate relative calibration between the two images. This issue can be seen in DMTN-061. Not clear how frequently this occurs. This can be fixed by fitting for the relative calibration and setting them as the Fr and Fn parameters for Zogy, or else ensuring that the LSST stack calibration is accurate. Another possibility is that the images are not being loaded for Zogy correctly or that a (already measured?) flux calibration should be applied to the pixels in the images before running Zogy.
