      Description

      Because the simulated galaxies we are using to configure the deblender are extended with very large wings, comparing the deblended flux with the simulated flux is deceptively difficult. The problem is that a large percentage (as much as 50%) of the simulated flux can lie below the noise level, where it is truncated in the deblender, making it difficult to compare the total flux of each object.

      It was recommended by Jim Bosch that running SingleFrameMeasurementTask on both the deblender output and simulated images will allow us to make a better comparison of the results.

      This ticket will implement a set of tests using SingleFrameMeasurementTask.
