+I spent much of this week finishing up DVO optimization, both for ingest and for relative photometry and astrometry.  These optimization improvements have sped up the relastro processing by a large factor (moving an N^2^ process to an NlogN process). As a result, I was able to demonstrate a full-scale relastro analysis (4 iterations) for ~7900 exposures in about 10 hours.  This is not quite as fast as one might like, but it makes monthly calibrations feasible for the full 3pi.
+
+I also finished up the improvements to the CR masking and source size analysis in psphot, and added the statistics desired for improved assessment of the difference image sources (for distinguishing the dipoles, for example).  Before turning on CR masking in the real processing, I need to run a somewhat larger test, but the other features can be used now in the standard processing analysis.
