 XXXX: look at minor axis
+
+Now, the point of performing galaxy shape measurements on the warps is the hope that the results will be
+better than the stack measurements. The following two plots compare these full force results with the psphotStack fits
+to exponential galaxies.

+We find that for both the major axis and magnitude the histograms of the difference from SDSS are narrower and
+peaked closer to zero.
