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

=== Eugene Magnier ===

 * finished up the psphot saturated star radial profile analysis, and it really helps a lot (see Bill's report).  Also fixed some issues with duplicate detections (using a mask to block re-detection of the cores) and negative fluxes in linear fits (at least in psphot; psphotStack was fixed earlier).
 * update the dvo schema and pushed changes into the trunk.

=== Serge Chastel ===
 * Tuesday off
 * Documentation of the "Who is the cluster?" software.
 * "Who is the cluster?" given to MOPS/Denver.

=== Heather Flewelling === 

 * czar for 2 days (including the day of mhpcc power outage) 
 * sas-subset : rsync://ipp0012.ifa.hawaii.edu/sas-subset  contains all raw files all filters for skycell.1406.028 (and likely other skycells as well)
 * sas9
   * wait for gene for dvo changes
   * built dvo for smfs (SAS_v8)
   * wait for bill/gene for psphotstack
 * sas-isp
   * attempts at processing isp-sas stuff is located here: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/IspSasProcessing
 * lots of sciency stuff with JT (not involving sas! )

=== Mark Huber ===
 * vacation

=== Bill Sweeney ===
 * Tested Gene's improvements to psphotStack to better model massively saturated stars. The number of false detections is greatly reduced around such objects.
 * Ran staticsky and skycalibration analysis for SAS_v9 which is the new psphotStack running on the SAS_v8 pixels. Made a configuration error so had to run this twice.
 * Started working on a design for software to manage "release versions" for IPP data. This is being done to support several requirements.
   * users need updated calibration information in IPP data. For example zero points for a stack or exposure. These change with re-calibrations, but we have no method for tracking this information and so we can't update the headers of fits files which are requested by users through the postage stamp server
   * currently there is no way to track which pixels the IPP used for to measure a given detection in the PSPS data base.
   * we need to distinguish "released" data from test runs in the IPP data base.
 * Iterated with Conrad on the interfaces for the postage stamp user interface project.
 * Investigated why some M31 warp data did not get distributed to MPG. There was a problem early on in the distribution set up. It didn't expect data in filters other than r and i. By the time we fixed the coniguration to distribute the data, the pixels had been cleaned up. Since we didn't build update cabability into the background restored system, I needed to do some time and energy to get the data to be regenerated.
 * Lot's of assistant czar work helping to manage the fallout from the MHPCC cluster power outage and various other strange problems. 

=== Chris Waters ===
 * Investigated the possibility of minimizing row-to-row variations by constructing 8 per-OTA correction images.  http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/GPC1_Bias_Pattern_Study This looks somewhat promising, although it will require some level of development.
 * Continued making w-band static sky stacks.  These should be finished soon, and we will be able to switch to using them for differencing.
 * Began work on background model warping.  Currently sorting out some WCS issues and trying to determine why the interpolation fails for a significant fraction of the output image.
