     8We have been fighting with hardware problems this past week.  One machine, ipp030, had a motherboard failure.  Cindy replaced it with the motherboard from one of the compute nodes (ippc10).  We had many repeated crashes of ippdb03 (backup database server), and have arranged to move its services to another compute node (ippc11).  We had a problem with the raid on ippdb00 (nebulous server), compounded by inconsistencies in the reported drive IDs.  We had multiple crashes of ipp026, and have removed it from the nebulous list for now.  It is unclear to me if this is just a string of bad luck, or if there is an external reason for multiple hardware problems.  Cindy et al checked on the load on the PDUs, but there does not seem to be any thing unusual.  A/C seems to be fine.

     10I have been making progress on improving the non-linear fitting for extended sources.  I improved the model guess by using a large set of fake data to generate a better set of relationships between observed moments and model parameters.  I also improved the speed of the non-linear fitting by (a) using fewer pixels for the fit than for the model subtraction (these had previously been coupled) and (b) allowing for a 1D PSF convolution (saves about a factor of 2).
