• MOPS czaring at IPP level
• Set SVN for operational files
• Helped Heather with nfs and eventually started to write a new tool to replace(?) nebdiskd.

• Only worked two days this week (vacation for three).

• IPP to PSPS test loop:
  • set-up ippToPsps (installing Java, Jython, scratch MySQL database etc) on development cluster
  • needed to add some tables and columns to test-gpc1 database (with Heather's help)
  • inserted enough metadata to test-gpc1 about a single camera exposure to run ippToPsps
  • code changes to get IN (initialization) batch working with new Batch class
  • missing primary header values in test smf files. Changed interface code to ignore these and proceed, with errors added to log
  • missing SOURCEID and IMAGEID in .hdr extension: can't interface with DVO without these

• tweaks to czartool after big changes last week
• created PSPS wiki 'News and Updates' page, linked to from PSI
• added some new plug-in queries to PSVO for stacks

• 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.
• 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.
• 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.
• 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.
• LAP code: Began rewrite of LAP code to deprecate quickstacks in order to speed up processing.
