ACS Cosmic Ray Rejection

These tables contain the parameters used by CALACS/ACSREJ in the pipeline, to reject cosmic rays from CR-SPLIT images only. Note that with MultiDrizzle added to the pipeline (~Sep 2004), image combination (including cosmic ray rejection) will be performed for any type of associated dataset, using the parameters contained in the MDRIZTAB reference files.
