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

=== Eugene Magnier ===

=== Heather Flewelling === 
 * automated addstar stage (survey task)
 * revert tasks for stack, diff, dist (added to stack.pro, diff.pro, dist.pro)
 * investigated magic, destreak, distribution failures- all were nebulous errors, except for a few destreak problems (which Bill investigated - destreak logic problem)
 * replicated all detrends (they all have at least user.copies:2)
 * liason duties (answering emails)
 * answering questions about installing IPP on mac & linux

=== Bill Giebink ===
 * modified DNSM code to include a "heartbeat" for camera operation
 * collected, reduced, and posted DIMM data for the week
 * operated RoboDIMM Thursday and Friday night
 * performed a couple of CPU transplants on IPP machines

=== Roy Henderson ===

 * attempts to load data at JHU:
  * prob with objIds - fixed
  * missing {{{SkinnyObject}}} table - added as a new extension
  * permissions/admin problems. Still working on it.
 * lots of changes to ippToPsps code after meeting with Gene, Jim etc - all implemented all in ippToPsps
 * wrote a perl script to parse PSPS schema in order to minimise work when changes are made

=== Paul Price ===
 * Propagate zero points from cam to diff.  Source lists from ppSub now have calibrated magnitudes.
 * Propagate FWHM from warp to diff for ppSub parameter scaling.  ppSub now doesn't have to measure the FWHM (at least for warps; not tested on stacks yet).
 * Diff failures:
  * MD06.077 failing due to bad reference stack (stack_id = 52606); fixed error code.
  * Every other fault=2 inspected was due to filesystem errors.
  * All fault=5 have dtime_script <= 3 sec, apparently due to difftool unable to find the SQL file.
  * Reworked all ippTools to put fault=2 (SYS_ERROR) when can't find SQL file (presumably due to NFS problems).  Removed DATA_ERROR because ippTools don't work on data (astronomical images or catalogues).  This should allow us to turn on revert for fault=2 only.
  * Reworked ppSub to be better about error codes and their translation to exit codes.
 * Add exposure comment to data store when publishing detections.
 * Stack failures:
  * "Stack list contains less than 2 elements" accounts for most of the fault=2.  Added "-min_num 4" to automate_stacks.pl and stacktool now requires min_num to be specified and >= 2.
  * fault=5 modes:
   * A bunch of failures in the relative photometry that doesn't make sense on reading the log.  They may be due to rebuilding the code mid-way and repeating.  Best to revert and retry.
   * dtime_script < ~ 10 are generally due to all (or most) inputs having few lit pixels.  Added "-select_good_frac_min 0.05" to automate_stacks.pl to correspond with BADFRAC in the PPSUB recipe.
   * Nebulous errors account for most of the rest, often reading from ipp004 from a range of machines.
  * Reworked ppStack to be better about error codes and their translation to exit codes.
  * fault=4 (PROG_ERROR) seem to be due to failure to find a PSF model, and then triggering a SEGV in ppStack; fixed SEGV.
 * Chasing down camera runs in ThreePi.Run5c.20100217 that didn't write all masks
  * 399/2655 = 15% have at least one missing mask (actually, this can be due to bad data quality at chip stage too)
  * Fixed camera_exp.pl to check that masks are written
  * Fixed warp_skycell.pl to ensure mask is available
  * Re-ran camera stage through pcontrol for bad runs

=== Bill Sweeney ===
 * monitored addstar processing (still a partially manual process) Released 2 versions of 3pi catalog. At the end of the week announced that all catalogs are available on the rsync server
 * telecon with Eric Morganson at MPIA, ipp meeting.
 * got sick. efficiency reduced for most of the week
 * added mode to magicdstool to deal with revert and cleanup faults. tested
 * wrote up notes on "optimized update proessing". Spent rest of week working on implementation. It is likely to be easier to finish than originally thought.
 * ran simtest to prepare to test changes for update. Found and fixed bug in ppSim.
 * debugged and fixed problem with destreak revert
 * answered lots of questions about postage stamp server. fixed a couple of bugs.
 * started working on optimized bycoord rquests
