    Description

      DM-15895 investigated the source of the bimodality in the HSC S18a fgcm run when comparing HSC r-band to Gaia G band.  Most of the relative offset between different regions of the footprint was due to differing throughput of the HSC r and r2 filters.  This ticket will add additional fit terms to fgcm to allow for these sorts of throughput offsets (which also applies to the HSC i/i2 filters).

            The main changes in the stack code are in the PR for `fgcmcal`.  The PR for `fgcm` basically has all the internal changes in the 3rd party code, external to the stack.

            Looks fine to me, brief comment included on the github and conveyed to erykoff in slack about differences (if any) between log and ln that are used in different places.
