+With the telescope down this past week due to shutter problems, we have been pushing on other, background processing which is needed.  This includes more analysis of the darks (still in progress), working on the deep stack for MD06, and starting the reference stacks for MD08, MD09, and MD10, which are now starting to be observed alot.   
+
+I continue to work on extended source analysis.  My attempts last week to improve the stability of the fits was not as successful as I hoped.  I have turned in another direction: I have modified the analysis for the Sersic model to first do a coarse grid search in the index and normalization, before allowing the rest of the terms to float.  I have been very happy with the results of this method so far -- the grid search gets us very close to the required index, and once there the fitting is much more stable.  I'll be doing more testing, and concentrating on a number of (unrelated) psphot issues that have been identified before this effort will be finished.
