      Description

      Per LDM-151 ยง5.4.1, we will fit a hybrid galaxy-point source model to sources for level 2 object characterization.

      Achieving the SRD requirements with respect to the measurement of galaxy shear will require detailed understanding of the procedure for fitting. In particular, this milestone will establish the requirements for:

      • The number of pixels typically included in the fit, and
      • The order and number of shapelet terms in the PSF.

      This milestone will also consider other, non-shapelet, approaches to convolution, benchmarking them on the same speed vs. quality metrics as shapelets.

      This work will be carried out using simulations and a placeholder galaxy fitting algorithm.

          All work has been performed to meet this milestone, but a technical note describing its conclusion is still under construction (DM-5447). This milestone will be closed as soon as that note has been accepted.
