Use template DCR images for image differencing

    Details

      Description

      DM-6382 creates template images of a field at arbitrary airmasses, which can be used to match the template airmass to the science image precisely to mitigate Differential Chromatic Refraction in image differencing. This ticket is to determine the best method to supply the new templates to image differencing, which may be simply to create a new exposure and ingest/process the template as though it were a real observation.

            It is now straightforward to generate DCR-matched templates for a range of observations, and those templates can be used for image differencing. Code is in https://github.com/lsst-dm/experimental_DCR/tree/nl_dcr_trial
