      Description

      This epic continues the work undertaken during S17 to prototype the NMF deblender.

      Specifically, over the course of this cycle we will focus on testing the new deblender with "hard" problems derived from both simulations and real data. We will focus on both demonstrating whether the NMF approach can get good answers (at least better than the current, SDSS-derived) deblender in the majority of cases, and that it avoids catastrophic failure modes.

      At the end of this cycle, we expect to be in a position to decide whether the NMF deblender will remain the focus of our development efforts in future cycles (and, therefore, be the presumptive choice for use in operations).
