     50 * Reprocessing Tests: Created z-band comparison, which has a less complete set of exposures.  This shows large gaps, most likely due to insufficient numbers of input exposures for some regions.  Checked that quick stacks have the expected noise distribution (S/N is a Gaussian with sigma = 1).  Checked dual-convolution of quickstack-warp diffs compare to single convolution diffs.  The dual convolution results in far more magic streaks.  Implemented a no-convolution mode for ppSub, and tested that.  This seems to be an improvement over any convolutions in the diff, but is still worse than pair-wise diffs (based on stack good_frac and magic Nstreaks).
     51 * Astrometry: processed first microtest data, and organized wiki page with results: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/GPC_BrightStarAstrometry_Microtest
     52 * Registration: identified bug that can stall registration at the beginning of a night if an exposure has summitExp.dateobs and rawImfile.dateobs that fall on opposite sides of the burntool cutoff (currently UTC 03:30). 
     53 * Detectability: fixed first batch of bugs, which should allow data that has not been cleaned to process correctly.  I have not yet tested data that needs to be updated.
