+
+ I've largely been working on comments from Doug F and Paul P on the photometric ladder paper.  Doug pointed out the higher scatter in my figures compared to the ubercal version, for the same regions.  I tracked this down to small number statistics (smaller areas used in my plots), failure to exclude the bad detections (bad flags), and failure to exclude enough of the galaxies (thus larger scatter at high |b|).  I'm still not completely satisfied, and am grabbing samples of the LSDatabase from Eddie to do more direct comparisons before I submit the paper.
+
+ I've started to work on the very bright stars in the deep stacks. These have too many false positives in halos due to poor subtraction of the model flux.  I have set up code to measure and subtract a radial profile (with circular symmetry).  The result looks good at the first pass, but I need to be careful about edge cases.
