 * PSPS
  * Continued loading demo month data, now approx 6000 exposures in Db. Issues encountered:
   * some duplicate exposures 'sneaked in', so wrote a script to generate a list from audit logs then Sue purged them from Db before merging
   * found bug (logic error) whereby code was not getting newest reprocessed smf data. Fixed query.
   * fixed bug arising after certain exposures (legitimately) failed, but caused all subsequent exposures to fail as well
   * loading halted when I encountered corrupt DVO database. Heather built me a new one for 3PI demo month
  * added two new tables and functions to the schema for handling detection and image quality flags

 * IPP
  * bulk of work was creating a database back-end for ippToPsps:
   * wrote 'createDb' script to generate the Db, complete with a revision table
   * table logging batch_id -> exp_id and various processing states. Populated from old audit logs
   * changed run script to use Db in place of old flat-file auditing
  * Czar for two days
   * Changed czartool to use a menu to be more in-keeping with the rest of ippMonitor
   * can now link from faults to a pages where logs can be located

 * Flat top significance images
  * Building stacks with updated software
  * Stacks produce significance images with peaked top
  * Stacks produce diff significance image with peaked top
  * All clear!
 * Writing PSF-matching paper
  * Text mostly done, working on figures/examples
  * Found small bug in noise model: changing scale of covariance matrix was introducing power
  * Measure covariance from PSF-matching at a small number of positions over the image and average
 * Processing czar:
  * Distribution server wasn't running; restarted
  * nebdiskd wasn't running, restarting was difficult because of Gentoo init script funkiness
  * Fixed warptool -advancerun and chiptool -advancerun
  * Merged dbconfig, ippTools, pstamp into operational branch and rebuilt
  * Deleted nebulous instances on full ipp015 causing warps to fail
  * Converted a couple of ppSub error cases to 'bad data quality': no sources to match, variance renormalisation out of bounds
  * Regenerated diff 56818/skycell.2213.067 and 56957/skycell.1117.097 due to corrupt file
  * Fixed corrupted raw file
 * Recovering after demise of laptop (needed to boot old machine via floppy to install Ubuntu)
 * Reworked locking in psThread.c to attempt to fix aborts
 * Turned diff statistics on

 * Masks: Finished mask work, and made a wiki page about the results: [wiki:GPC1_FPA_Mask_20100525]. Created final median static mask, and sat down with the camera team to discuss what could be done to minimize the effect of detector issues.  Merged mask stats/software revision code into the trunk.
 * Work on JPEG creation for warp and later stages.  JPEG creation code and tasks are largely finished.  Incorporating stack association idea into this branch to allow multiple stack_id entries to be grouped into a single object on the basis of the projection center.
 * Modified ppSkycell to output fits images as well as JPEG images.  Still need to do some work to add usable header information to these files.
