      Description

      This is regarding the recent discussion in the science-pipelines room where there has been discussion about using composites to get components of a calexp.

      In CameraMapper we will add metadata readers with object constructors for wcs, calib, and visitInfo.

      The API to get the components and entire calexp would be

      wcs = butler.get(‘calexp_wcs’, dataId={…})
      calib = butler.get(‘calexp_calib’, dataId={…})
      visitInfo = butler.get(‘calexp_visitInfo’, dataId={…})
      calexp = butler.get(‘calexp’, dataId={…})
      

      (note: we were originally going to use butler composites for this, but decided this is a better way to go)
