Source Extractor using wrong gain, saturation #9

After cross convolve, the following warning is thrown:

MeLOn CheckPoint [conv_align_skysub_Roman_TDS_simple_model_R062_37396_8.fits]: Run Python Wrapper of SExtractor!

Should default to gain=1, saturation=100000. The values in this error are default to SFFT. We need our defaults to be 1, 100000.

I updated my forked SFFT package (https://github.com/laldoroty/sfft) to allow choosing gain=1, saturation=100000, but I think we should leave this open and figure out if we need real gain/saturation values in headers. Or if these values are always correct because it's a sim...?
