     58 * Dark studies: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/Background_Dark_Model
     59 * Noisemap/false positive studies:
     60  * Changing the binning areas in the noisemap changes the results, but not in a dramatic way that would account for the observed remaining false positive results.
     61  * Confirmed that as the noise increases in a noisemap cell, it also becomes increasingly non-Gaussian.  However, it does not seem to be so non-Gaussian  as to explain the false positive rate.
     62  * Looked at the trend of false positives with changes in detector GAIN.  This works in the way we want, but although the cells with presumed bad gain values have a higher false positive rate, the small number of these cells prevents them from having the majority of the false positives.
     63  * Confirmed that the false positive rate decreases dramatically if we enforce a 5-sigma detection limit on measurements.
     64 * Change to psastro to record reference catalog name in the PSREFCAT header keyword.
     65 * Confirmed date range for various dark/noisemap changes, and queued new detrends to match those changes.
     66 * Confirmed that the A/B mode dark variations do not correspond to the status of the glycol.
