    v9 v10  
    3838    Problems show up in centroids off the edge of the Footprint.  Test:?  Status:  mostly written

    40   Tune galaxy modeling policy values:: 
    41     We have a number of policy values for the galaxy modeling that we haven't really tried tuning too much - or rather, we last tried tuning them when we had a serious bug that could have overwhelmed any improvements we might have seen.  We should at least try growing the footprint by different amounts and using different shapelet orders to approximate the PSF.  Test: Look at pipeQA's (psf - mod) or (cat - mod) if we can get it.  Status: code written, just need to do runs with different settings. 
    42  
    4340  Corrected astrometry.net index files (KSK):: 
    4441    An update to the index files in /lsst2/krughoff/astrometry_net_data/imsim-2011-06-20-0 (likely called /lsst2/krughoff/astrometry_net_data/imsim-2011-06-20-1) will be released as a package.  Status: Package release requested. 
     
    4744    There is evidence of gradients in the most extreme edge chips.  This suggests an error in the application or production of the calibration flats.  There  is also evidence in the photometric zeropoints that the analytic model of the vignetting is not accurate enough to model the true vignetting function to the 1% desired over the full focal plane.  Status: Looking into the flat production.  Comparing flats produced photon by photon to the analytical model.

     46== Things we'll keep working on until someone says "code freeze!" == 
     47 
     48  Better diagnostics and experimentation with galaxy modeling (UCDavis):: 
     49    Some funny things are still going on with some datasets: galaxy models fluxes are systematically offset from PSF fluxes by too much, and objects that are clearly stars are being fit with extended models.  We're making rapid progress, but it's not clear how much we have left to do.  See GalaxyModelingToDoList for more details.

    5051== Things that should '''not''' be included == 
     
    5758   They are ready-to-merge, but let's hold off until post 3000
