... Hanisch provided me with the ``right'' answers for the stars in the simulated cluster, so it's easy to determine the error of each magnitude determination: find the star in the truth file that falls nearest to the position of each star in my photometric output, and compute the difference between their magnitudes. The question of how to encapsulate these magnitude differences in an overall figure of merit for the reduction procedure deserves some thought. ...
