Usage: Start the app with -e EXT to define data's extension, otherwise we read the [0, 1, or SCI].data in the selected FITS. // By default a 0.5 threshold is applied to acquire the binary CR mask. Lower the threshold to include more peripheral CR pixels and apply morphological dilation to enlarge detected CRs. // Predicted CR probability map is appended to a new FITS copy, use the Download button to append the edited binary mask.
