    Description

      34 = 27 erykoff + 7 nlust

      Beginnings of HiPs maps:
       
      Improvements to photometric calibration

      • Start on implementation of compensated aperture fluxes
      • Extend FGCM to support camera rotations needed for LSSTCam

       

       
      Eli's Detail Sprint Plan:
      gen2-> gen3 conversion for fgcm outputs
      Fixing Single Frame astrometry errors on DC2
      Propagate astrometric scatter up to VisitSummary
      DC2 Gen3 Sprint: Astrometry QA + Visualize MaPs
      Consolidate each set of per-tract maps into a per-survey map
      Generalize FGCMLoadReferenceCatalog - catalog transformation tools (color terms and selectors) and add to meas_algorithms

          At the close of this epic, HealSparse property maps are now built as start of standard processing, and many improvements have been made to fgcmcal, in particular about gen2/gen3 parity. For HiPS image making, I made what I believe is the first python implementation of making HPX WCS headers suitable for HiPS images, and the first implementation outside of Aladdin hipsgen. Building HiPS images in a pipeline now only needs the butler to be healpix-aware.
