• We have seen images that have been generated by OMFLATFIELD that contain pixel values that have been set to the BLANK keyword value. This occurrs due to the Flatfield being zero for these pixels. The quality array has been flagged to the value of 16 for these cases. The image has been modified to contain the value zero as a temporary fix.
