     36 * Dark: Identified that the previous quadratic temperature model was established for a different (warmer) temperature regime.  The current temperature range appears to be in the nearly linear tail of an exponential.  This helps explain why fitting with a linear model was yielding less noisy data: a quadratic is generally unjustified by the data.  Constructed a new full exposure dark model that uses at most a linear temperature dependence, and confirmed that it introduced less noise than the current dark (~2 counts compared with ~8 counts), as well as being successfully verified against random dark data.  Promoted this dark to the currently used model.
     37 * Offnight diffs: These do not appear to be generated at the moment, and it looks like this will require a day or so to fully debug.
     38 * LAP processing: Queued SAS2.123 and SAS.footprint for gri using the new dark.  Dropped LAP/14hr y-data to free diskspace and to prepare for a jump to 16hr.
     39 * Diskspace: Rewrote diskspace accounting script to account for diskspace better. Queued chip-stage pattern files for cleanup, as these had not been cleaned before.  As they are regenerated by the update process, there is no reason to retain them.
     40 * LAP code: Began rewrite of LAP code to deprecate quickstacks in order to speed up processing.
