proton_scale extracts the BACKSCAL keyword and average soft proton intensity from the detector map for a specified region. These values are necessary in the spectral fitting process of multiple regions which are linked.
Warning and requirements: proton_scale is part of the esas package integrated into SAS, but it is limited to work within the esas data reduction scheme. This is specially true wrt the structure and names of the input files. In particular, proton_scale assumes that another task from the package, mos-spectra, has been successfully run for the exposure to be used.
