Serge Chastel

• Enlarged storage nodes disk view in czartool
• Fixed a few lost otas
• Updated ppMops for trails fitting
• ippc63 replicates ippdb00 nebulous database

Heather Flewelling

• czar - registration problems on monday - I fixed them manually, chris committed fixes to fix them more permanently
• ipptosps
  • schema changes for new improved columns in objects
  • changes from staticsky to skycal
  • note to self: with new tag and new dvo schema, kill all screen sessions and recompile dvograbber or else you get junk in batches.
  • friday afternoon: sa8 is loading with new dvo schema, skycal, and new ipptopsps schema.
• dvo
  • skycal is implemented in addstar and committed in trunk
    • to be used instead of staticsky
  • Sa8
    • first attempt to build - failed with fault 2 and I don't know why
    • second attempt worked
    • relphoted with special gene command
  • ThreePiQ2
    • failed, two problems:
      • 2 minidvodbs are not quite right - they pass dvoverify but cause lots of messages by dvomerge
      • perl script grows too big while holding onto the messages caused by dvomerge (gene found this)
    • rebuilding, without the 2 funky dvodbs
  • skytable.fits - whatever problem it was, it's not repeatable. Going to ignore it for now...
• psps
  • investigated on the sandbox objects - ken had found funny values in the columns - I expect this is due to the swaps of column names, the batches themselves look good.
• science stuff for durham

Mark Huber

Bill Sweeney

• Continued working on psphotStack. This program takes a long time to run and thus debugging is slow going.
• Found and fixed the cause of the memory corruption problem that we worked on last week. Turned out that the code was using a non-thread safe data structure.
• Found and fixed a race condition that caused a SEGV in the extended source fits.
• Modified psphotStack to enable Detection Efficiency measurements.
• Started an exhaustive analysis of the memory usage in psphotStack. With all of the bug fixes and optimizations introduced over the past several weeks it now completes in reasonable time (1-2 hours) for a skycell near the galactic plane, but it still grows to over 32 GB in virtual memory usage in those fields.
• fixed a postage stamp problem that I inadvertently introduced last week.
• updated the list of preferred data_groups for postage stamp requests. With the switch to the ipp-20120802 tag that code is now deployed.
• found and fixed cause of an assertion failure in the extended source fits.
• 2 days as processing czar.

Chris Waters

• Writing.
• Compared stacking methods to look at the stack Nigel made by simple means. Wiki page on results: ​http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/Stack_Rejection_Discussion
• Fixed bug in burntool that would result in a segfault for certain input tables.
• Finished nightly_science.pl change to implement W-S diffs for the ecliptic.
• Ecliptic finished, launching new LAP hour.
