Stacking Artifacts in Mosaic
I'm using 1.077. I previously had done multiple large mosaic projects with no issue. However, this latest attempt has some odd artifacts present that I can't eliminate. As you can see in the attached image, they are aligned with each other and seem to come from the same source. I did an integration of a single panel of the mosaic and the artifacts are not present, so it does seem to be associated with the mosaic stacking process.
I have attempted to do the mosaic stack with no calibration files at all and the artifacts are still present, so the source must be in the image files themselves.
