AIJ's Data Processor (DP) module has outlier rejection in the Image
You'd have to fiddle around with it (i.e. the radius and threshold
settings) to see if helps solve your problem.
Note that the outlier removal function may affect photometry
somewhat when pixels are corrected within the steep portions of the
PSF. If there is only one pixel at the peak of a tightly focused
PSF, it may also be reduced to the values around it. The function
basically replaces outliers relative to the pixel value and
threshold setting with the median value of the pixels around the
pixel in question.

Hi everyone! I'm currently working on a project to reduce cometary
data for photometry, and we're looking into methods to get rid of
artifacts in the images from cosmic rays and other radiation
sources. We have some leads for cosmic ray rejection routines, but
other radiation artifacts are a little more difficult because they
don't tend to look like cosmic rays (or anything else) and there
aren't a lot of routines available to get rid of them. I was
wondering whether anyone had any suggestions for tools in
AstroImageJ that might be useful?
Thank you in advance for your time!
