      Description

      Ultra-faint dwarf galaxies are usually found from photometry of their bright member stars. However, these stars can be superimposed on the faint, unresolved light of the galaxy, which biases the measurement. We need to measure the PSF flux with a local background subtracted.

      I originally started writing this as a background-subtracted PSF flux measurement algorithm, until I realised that simply measuring the background is all that's required (and dealing with inheritance in the measurement algorithms is annoying), and it can be subtracted from other measurements as well as the PSF flux.
