1. Saturation & Bleeding.

In order to produce stacked images of our galaxies that are picture-book perfect, we must fix the bleed trails from saturated stars. Removing these artifacts will allow for a "clean" image; however, we will also lose all information about which pixels were saturated and where the bleed trails were. So, we are only applying this correction for the pretty-picture version. First, we need to check the saturation values for each chip, and revise the header if need be. We will need to revise each individual extension. To fix this:(Note: these values may change)

ccdproc will then be used to create new bad pixel masks (containing the saturated stars and bleeding columns) for each image, and fixpix will be used to interpolate over these regions. Running mscimage on these images produce the geometrically corrected images known as fmim's (for fixed mosaic images).
