 * processing czar 04-12-2010
 * Taught Roy about processing tasks as they came up.
 * sorted out ISP summitcopy - datastore issues. Erik Small made ISP datastore
   behave more like gpc1, Bill figured out how to get around problems like this
   in the future.
 * ISP registration - ISP images now register to camera stage, with camera
   label (only the OBJECT ones, ones which could potentially be processable),
   ISP registration merged in with gpc1
 * created ISP wiki of everything I could think of about ISP processing:
   * http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ISP_Information
 * stack test of different plate scale (0.0258): label is
   MD04.20100415.scaletest.0258 , consists of 8 MD04 z band images from
   20100412. These are stuck due to failed warps (I need to sort this out). TESS_ID is MD04.V1
 * answered UIP's questions about processing ISP data - this is still in progress
 * added tess directories to ifaps1 (to make it more useable)
 * answered ifaps1 user questions throughout the week
 * Helped prepare for IFA Open House
 * manned PanSTARRS booth at IFA Open House
 * Helped Mike Lum (VYSOS data reduction) - this is still in progress

=== Bill Giebink ===

 * Prepped PS2 pier for ground penetrating radar team
 * Swapped ipp037 CPUs for new ones
 * Worked with radar team to map pier

=== Roy Henderson ===

 * PSPS
  * Installed the DXLayer on Maui cluster (a few issues, nothing major)
  * Created and loaded 1000 batches of real data. Handful of errors: see below

 * IPP
  * Added to processing czar wiki page
  * Improvements to error handling in ippToPsps
  * Changes to arguments for ippToPsps run-script (can run for a single exposure rather than whole label)
  * PSPS survey 'type' now taken from the gpc1 Db (using 'dist_group')
  * Bugs uncovered from PSPS loading:
   * Empty {{{ImageMeta}}} tables created if chip extension missing from input FITS: fixed
   * NULL values in smf files going into FITS output and getting blocked by loader: fixed
   * 0.00 values for flux getting blocked by loader: investigating

 * MOPS detection woes:
  * Inserted fake asteroids from Larry into chip stage products, manually ran through warp and diff, and shipped results.  Based on detection efficiency measurement in psphot, only about 35% of asteroids (about 100 asteroids) from the input set are bright enough for detection.
  * Found SDSS report of 0.4 mag bias in asteroid photometry catalogues
  * MOPS photometry corrections don't appear to correspond to asteroid colours measured by SDSS
  * Re-running fake asteroid data with larger (10x) set of inputs from Larry
  * Depth of diff photometry appears to be g ~ 21 mag --> V ~ 20.6 mag.  Chip is going to g ~ 21.9 mag, so should be doing better.
  * Shallow depth appears to be resolved with more careful combination of variance+covariance at diff stage.  Recovered around 0.8 mag.  Sent detailed report to ps-ipp-users and ps-mops-dev.  Requires further work before merging into production system, especially worried about impact on Magic
  * Determined correct photometric corrections for MOPS: 1 mag offset in g appears to be ~0.4 mag catalogue bias + 0.5 mag photometric correction error.
 * Discovered a bug in "stacktool -definebyquery": wasn't grouping by tess_id.  Inputs to MD.preDM.20100409 stacks have heterogeneous tess_ids, but this hasn't affected the stacks produced because "stacktool -inputskyfile" ensures the correct tessellation is used.  Set failures (from insufficient inputs with the correct tess_id) to 'drop'.

=== Chris Waters ===

 * Out for two days due to illness.
 * Finished first draft of detectability server. Waiting on the PStamp interface to stabilize before committing the final version.
 * Started work on matching IPP parameters to SDSS star/galaxy classifications for SAS.
