      Description

      Data processing of CFHT and (soon) simulated LSST images in the context of DC2 have the need to use an absolute sky map such as the rings sky map used in the HSC reprocessing. To do so, modifications of the MegacamMapper.py and lsstSimMapper.py have to be done.

       

      The next step would be to move the default of the skymap type to obs_base in the cameraMapper and let each obs package override the pixel scale and possibly the number of rings.

            I'm assuming this ticket is no longer relevant since we are doing DC2 processing with a skymap. Jim Bosch does that imply that RFC-438 can be adopted?

            DC2/imsim does indeed now have its own skymap configuration, and that will override any new default we make.  But I do think this ticket and RFC-438 should remain open, as we haven't changed the global default (which would affect obs_decam, obs_cfht, and the real obs_lsst instruments), and we still probably should.
