• MD04-r very deep stack release. MD07 exposures finished running through warp, MD07-y refstack and test samples made.
• continued working through ppStack and ppSub testing
• Out sick Tuesday, Czar Friday

• Modified database schema for diff stage to handle case where difftool -definewarpwarp selects two exposures but for differencing but they actually don't have any skycells in common. This was trickier than we expected but in the end we solved the problem.
• In the process of testing this feature we discovered an inconsistency between the production gpc1 database and the replicated version. An extra row exists in the replicants. Spent several hours with Serge attempting to determine how this might have happened. No conclusions as yet
• Gathered some M31 warp exposures to demonstrate the severe false streak detection problem that we are having with M31 this year. This involved reprocessing some exposures and writing scripts to copy the data to a directory on one of the stare nodes and run the ppSkycell program to generate binned jpegs.
• Started working on adding a new feature to the postage stamp server to allow users to select images that have the background correction restored. This has been requested by users looking at large sources. Something that is different here is that we are going to do processing which has not been run before. That is we won't require that a chipBackgroundRun exist for the exposure. This is something new for the postage stamp server, but in this case it appears to be something that we can implement with reasonable effort.
