      Description

      Direct coaddition involves applying a relative astrometric solution (as produced by the Single Frame Pipeline, 02C.03.01) to input images, warping them to a common coordinate system, and coadding the pixels. This includes generating a combined PSF model based on the inputs.

      This functionality is required by LDM-151 §5.2.1. It is described by LDM-151 §§5.2.2.1 & 5.2.2.5.

      Per this milestone, it is possible to generate direct coadds but we impose no requirements as to computational performance or algorithmic fidelity.

      In practice, this is a port of existing functionality from HSC, which is itself mostly just a refactoring of the existing LSST pipeline with relatively minor algorithmic improvements.
