IPP Progress Report for the week 2012-09-24 - 2012-09-30

(Up to IPP Progress Reports)

Eugene Magnier

  • preparation work for PS1 seminar on friday 9/28 and UH proposals.
  • worked on the comparison between my DVO database and the subset of detections sent by Eddie. I found that there are inconsistencies at the few millimag level, but there should be no difference above the floating point errors. I eventually tracked this down to an inconsistent calibration set from Eddie -- he thought I was using the regular version, but I was using the 'noref' variant which he had sent.

Serge Chastel

  • 64-bit bitwise and with MS SQL
  • Czar on Wed and Thu
  • ppMops

Heather Flewelling

  • I was sick for 2 days...
  • liason requests - there is currently no easy to find description of what the latest and greatest SAS and 3pis are, which makes it difficult for postage stamp users. I created the very basic http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/SASand3Pi to give a little bit of help.
  • I spent a while tracking the ndetections = -999 problem in psps. see here: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/SA9ndetections
    • There are 74k of thsee
    • 12 k come from a failed batch (this batch is out of range) why did it get ingested in psps?
    • 60 k fall outside of some range .. however... Heather doesn't understand why some of them got ingested anyways.. Heather can't find the batches that contain them...
  • heather volunteered for a talk on tuesday (WEDGE)

Mark Huber

  • MD09: nightly stack photometry sample 98% complete on the raw/unconvolved stack.
  • MD02: trying to make an improved refstack for 2012..
  • midnight registration check-ins and dealing with systems that lose ability to mount various data disks..

Bill Sweeney

  • Most of this week was spent investigating the consistency of the stack photometry imported into DVO and from there into PSPS. TODO: add conclusions of this study
  • Implemented improvements to ppstamp. The postage stamp extrator program
    • On request, read sources from cmf or smf file and create an output cmf file containing just the sources in the region of interest
    • Use the header information from the "astrometry" file since it contains the results of the psphot and psastro analyses. When deployed this will insure that the calibration information from the image is included in the header.
  • Spent an inordinate amount of time dealing with some of our nodes that keep hanging.

Chris Waters

  • Defined new LAP queues that will complete the sky. The current queue covers through 24h, the next through 4h, and the final one the less well covered 4h-9h region.
  • Finished warped background code, removed hard coded values that I had set for testing, and removed/psTraced the debugging statements I had been printing out. I'm not totally happy with the final binning factor, but that seems to be dictated by cleanly resolving the interchip gaps.
  • Cleanup: Sent a large fraction of the LAP warps to cleanup. I'm retaining those warps that have any skycell within 10 degrees of the galactic plane.
  • Updated pointing data extraction code for Ken, and unsuccessfully set it to run as a cron job by the ippm user.
