      Description

      The current implementation of aperture corrections in meas_algorithms' CorrectFluxes class is broken, and should not be replicated in meas_base:

      • it only works when the PSF model is correct
      • it doesn't work when the aperture to correct to is larger than the PSF model image size
      • it doesn't propagate the uncertainty in the aperture correction

      We probably need to do this by estimating the aperture correction and its errors on single frames, using the PSF stars (not the PSF models), then attaching that information to the Psf object to be retrieved and coadded by CoaddPsf.

      JK: In PMCS this would be 10% Bosch J 50% Krughoff S and 40% Owen R
      Breakdown: jbosch 10%; krughoff 50%; rowen 40%
