      Description

      (I thought this ticket existed, but I can't find it).

      In production we will almost certainly want to use a pre-defined set of stars to determine the PSF for each visit.  Advantages include:

      • The ability to use deeper data to reject compact galaxies
      • The ability to use other bands (e.g. NIR) to reject compact galaxies
      • Less stochasticity in PSF estimation
      • More robust in the face of bad data (e.g. clouds)

      It's a little tricky as we need decent astrometry before running the PSF estimation code.
