+I am running into a couple of problems with the M31 images and need to
+consider what this means for the footprints and for the CR masking.
+
+* The background modeling is not doing a great job of representing the
+  surface brightness of M31 near the core.  I'm concerned that there
+  is still a small offset between the grid model and the input image.
+
+* The footprints are outlining some low-significance regions which are
+  clearly instrumental
+
+* The CR masking should not be going to the low-surface-brightness
+  levels that the footprints need.
