... If two or more spectra have been taken under the same conditions, a very efficient way of removing particle hits from the raw data is to replace pixel values with large deviations from other observations with a local estimator, as done in the command COMBINE/LONG . If multiple images are not available, cosmic ray hits have to be filtered out by a different method. ... where subframe defines the region to filter. ... This step is done twice to remove the hits on the sky on each side of the object. ...
