Sample galaxy photometry fits

The plot below gives the first page of output for one of the runs of my fitting code. The black dots show the V magnitude vs. aperture points. The purple line is the best fit. Red points were excluded from the second round of fitting because they deviated too much from the original best fit. The dashed line at the top represents my derived total magnitude based on the profile fit. Note that most of the galaxies are extremely well-behaved, even though the photometry usually comes from multiple sources. You can see cases where there are not very many points, or where some points had to be excluded.
