     31 * Identified issue with scaling of warp backgrounds for stacking.  This then led to the realization that due to the PATTERN.CONTINUITY correction, the background models for adjacent chips have possible offsets relative to each other.  This suggests that the background models need to have a similar continuity correction applied as well.  This will ensure that the models produced by the warps are "smooth," which should in turn eliminate the scaling issues in the generation of a stack background model.
     32 * Worked with Denver on a new test set of WW diffs for trail fitting.  This suggested that ~15% of the expected trails were not being fit, likely due to psfQf issues.  As the expected cost of fitting all diff detections with an extended object fit should be small, I'll work on implementing this option.
     33 * Fixed interpolation issue that was slowing down psphot.
