Counts subtracted across whole image

[dkrolikowski]

Hi! I'm updating a previous spectral reduction code to use astroscrappy instead of cosmics.py, and am encountering an issue with the cleaned image. When I run both cosmics.py and astroscrappy on the same image with the same parameters, the cosmic ray mask is essentially the same, but the cleaned image is different. The result from cosmics.py seems right -- the cleaned image is different where the cosmic rays are. However, the result from astroscrappy is not the same as the input image anywhere, and has hundreds of counts subtracted in every pixel across the entire frame. I'm not sure if there is a background subtraction issue or something, but I do not input a background image. Has anyone encountered something like this, or have any insight on what the problem might be? Thanks!!
