magnitude, model  Just as the PSF magnitudes are optimal measures of the fluxes of
stars, the optimal measure of the flux of a galaxy would use a matched galaxy
model. With this in mind, the code fits two models to the
twodimensional image of each object in each band:
1. a pure deVaucouleurs profile, and
2. a pure exponential profile.
The bestfit model in the
rband is fit to the other four bands; the results are stored as the
model magnitudes.
Details, including a very important warning, can be found here.
