    Description

      In preparation for running an end-to-end comparison of large scale processing with the HSC and LSST stacks, we need to update the configuration to reflect currently understood best practice.

      In general, we expect the default HSC configuration to be better understood and "battle-tested" given that it has been used for science-grade data releases.

      Audit the default configuration of the full LSST stack (from ProcessCcdTask through multiband coadd processing). Where LSST defaults differ from HSC, update the LSST configuration to match the HSC equivalent unless there's a clear reason why LSST's default should be different. When it's not appropriate to update the LSST configuration, add an override to obs_subaru.

      In some cases, the LSST and HSC stacks have diverged so that a direct transfer of configuration options isn't possible. Where an equivalent can be found, take advantage of it. Otherwise, stick with existing LSST defaults.
