+ * lots of discussions & investigations with Chris to understand the real impact of the CONST vs IMAGE weighting scheme on the false positives.  there was some confusion over versions and recipe keywords which we finally worked out.  final conclusion: the CONST weighting enhances the sensitivity to faint non-psf-like artifacts in the data.  as a result, the false positive rate is higher even when boosting the variance.  We decided to go with CONST weighting anyway and accept the impact on false positives to avoid the faint end bias.
+ * pointed Doug & Eddie at MD09 and MD10 data processed with CONST to confirm the faint end bias fix.
+ * Roger & Bertrand reported some corrupt files in the released DVO 3pi database (2012.06.06). I updated dvoverify to run in parallel, ran it on the database and found the problem files (and a few more).  I repaired the problem files with the backup copy from 2012.05.09.  
+ * generated statistics and plots on the true and false positives as a function of filter and RA,DEC: [wiki:PS1_3pi_DVO_20120606]
+ * worked on finishing the photometry reference ladder paper.  sent to co-I's on Friday, to consortium on Jul 9.

  * ipptopsps improvements 
    * to get more things into object table in psps, we should really be modifying the dvo schema: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/DvoSchemaChangeProposal

  * MD10.refstack.20120705 selected chip-warp "test" reprocessing with new tag (ipp-20120626) and reftest samples made on stsci nodes after debugging setup. tighter input FWHM constraints from ppStack tests have helped reign in the convolved stack target PSFs but have highlighted a known problem of odd convolution that haven't had the chance to properly trace out in the ppStack tests. stalled until finished tracing out.
  * MD staticsky finished for all fields since fault is intermittent, revert solution for now... skycal problem found, needs to be tuned more appropriately for at least MD.refstack NRAW INST.MAG.RAW in own reduction config group.
