     46 * False positive rate.  Examined the false positive rate in the footprint data, and identified clear positional dependence of these false positives.  Comparisons of true image variance against the variance maps shows the same position dependence, suggesting that the variance maps are not correctly modeling the image variance.
     47 * Constructed noisemap model.  To add in the correct variance, I worked on adding a noisemap detrend type to the IPP configuration, and built one from bias frames.  Preliminary results suggest that this creates a variance map that better models the true image variance, and as a result, we find fewer false positives.
     48 * Summary and plots can be found at https://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/Background_Dark_Model
