 * chased down lots of processing problems
   * thousand of diffs failed, a full ipp016 was the cause, and some incorrect queries also caused problems. Bill and Paul helped out to debug this mess.
   * a few failures from each stage, mostly caused by the 0 byte neb bug. These have been dealt with, and Chris put in a fix that prevents them.  The 0 byte bug often occurs when there is a high load on a machine.
 * manned summitcopy and registration again, since there was stuff to download. investigated registration failures. 
 * figured out which raw files exist only on cabinet 2.
 * started copying megacam files into nebulous, about halfway done. (do 'neb-ls megacam' to find them)
 * started md09 processing. working on diffs and greater.  things are distributing. yay.
 * started md10 processing. chips are in, should go through to warp this weekend.
 * created a nebulous volume log on wiki. http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/NebulousVolumes
 * mask fractions for random chips and warps in throughput.20091104:

=== Bill Giebink ===
 * Got DIMM operational by repairing relays; serviced DIMM
 * Located and prepared requisitions for replacement and spare relays.
 * Attended scaffold training.
 * Spent a small amount of time on realtest.
 * Worked with Tom and Steph to setup a laptop to serve accelerometer data.

=== Paul Price ===

 * Stack photometry
  * Warp compared with warp: 0.016 mag (aperture) to 0.024 mag (PSF) scatter
  * Warp compared with stack: 0.076 mag (PSF) scatter
  * These STS warps have bad PSFs!  Generating own stack with "good" inputs failed because bad PSFs despite iq_m[234] being decent: double images and/or triangular PSFs.
  * Kepler is sparse in terms of PS1 coverage; ditto SA92.
  * Using Gene's flattest exposures.  Photometry comparison residuals:
   * warp-warp       PSF     0.010
   * warp-warp       Aper    0.010
   * warp-stack      PSF     0.016
   * warp-stack      Aper    0.014
  * Very pleased to see Nigel's values photometry comparison plots: good aperture photometry suggests stack pixels are fine.
  * Using simtest to verify that stack pixels are fine.
  * Discovered RA=0 boundary bug in DVO/getstar
  * 1 simtest stack failed; no time to investigate
  * Simtest run in /data/ipp022.0/price/stack/simtest
 * Fixed headers (WCS, concept values, software versions) for unconvolved stacks.
 * Threading for pmReadoutFake, trunk@26202.  If there are problems with this while I'm away, "svn merge -c -26202" should remove this change.
 * Fixed division by zero in magic_tree.pl that was preventing STS processing.
 * Preparing for UK trip.

=== Bill Sweeney ===
 * Worked with people at MPIA to get the current version of the IPP built and  installed
   at their site. 
 * Installed a data store at MPIA for them to use to submit postage stamp requests
 * Modified the ipp data store tools to work through a proxy server.
 * Helped monitor and debug issues in the destreaking and distribution portions of the pipeline.
 * Figured out why diffs were taking so long to bundle. There was a bug in the pending query that caused runs to get bundled multiple times. Fixed this and deleted the duplicates from the data store.
 * Finished postage stamp server "get_image" functionality. This will allow users to randomly select and download gpc1 data through the postage stamp server.
 * Added the ability to select psf, cmf, and background model image to be included in postage stamp data products.
 * At this point the processing portions of the postage stamp server are functionally complete. (The documentation needs to be updated though).

=== Chris Waters ===

 * Crosstalk: Finished and tested crosstalk masking in psastro.  On
  test exposure, correctly identified and masked all crosstalk
  artifacts known to follow the rules defined by John Tonry.

 * Data quality statistics: Wrote new task/script/tool group to create
  fits table bundles of exposure statistics for transfer to OTIS.
  All code is written, but no testing has been performed to confirm
  functionality.
