(Up to [wiki:IPP_Progress_Reports IPP Progress Reports])

=== Eugene Magnier ===

=== Heather Flewelling === 

 * processing czar for 2 days
   * taught Roy about different pantasks and how to restart them
 * created sky brightness plots for Ken
   * Ken posted these on the ps1sc wiki: http://ps1sc.ifa.hawaii.edu/PS1wiki/index.php/SkyBackground
 * isp processing
   * sorted out ppImage/psastro problems
   * working on automated nightly processing of isp data

=== Bill Giebink ===

 * Continued working through PS2 AC controller settings
 * Ordered more DNSM parts (hydraulic fluid, hard drives, etc.)
 * Corrected ipp037 RAID card wiring

=== Roy Henderson ===

 * PSPS
  * Bulk of work was finishing new FITS -> CSV code for the DXLayer.
  * Real data successfully loaded on sandbox with new schema
  * Helped Sue work through an ODM bug on the Maui cluster
  * Began design of recovery system with Conrad

 * IPP
  * IPP processing training camp with Chris and Heather
  * Wrote wiki page outlining processing czar duties

=== Paul Price ===

 * Sent muggled ThreePi.20100330 to MOPS
 * Set 3pi self-diffs to 'drop' state
 * Updated ppCoords to take streaks file, and to produce ds9 region files.
 * Investigating magic triggers: lots of "grass".
 * Processing czar
  * Set several tens of failed nightlyscience stacks to 'drop' because input data is ancient and gone.
  * Set LOTS of data to clean
 * Investigating claim of diff photometry not going deep enough
  * Playing with a single chip TTI pair through warp and diff
  * Instrumental detection limits: chip = -6.9 mag, warp = -6.6 mag, diff = -7.4 mag (all should have the same zero point) --> diff is reasonable, compared to chip
  * Worrying about covariances again: something goes missing at warp, which appears to be the covariance.
  * We have a variance map and a covariance "pseudo-matrix" to describe the noise properties, and these two cannot be simply added at the diff stage.  Have a solution that could benefit from some simulation to verify.
