 === Sersic Index ===
 If we look at the sersic index for all galaxies we get the following histogram. The hisogram on the right shows the counts for pure disks and bulges. We see that the fits for bulges are clustered around 4 as expected while disks mostly have values near 1.

 === Radii ===
-If we compare the measured widths with the source sizes we see effects that are not understood

 The following plots compare the measured semi-major axis with the disk scale length. The plot on the left shows all pure disks while the plot on the
