A function in the
MastMissionsclass that can read products into memory.For FITS files, we use
astropy.io.fits.open. The product files are downloaded and cached by Astropy, and then read into aHDUListobject.For ASDF files, we use
fsspecandasdf. Our downloads for Roman data are redirected to S3, so these files are not downloaded and are streamed directly intoasdf.AsdfFileobjects.
