IPP Progress Report for the week 2010.04.05 - 2010.04.09

(Up to IPP Progress Reports)

Eugene Magnier

Heather Flewelling

  • processing czar for 2 days
    • taught Roy about different pantasks and how to restart them
  • created sky brightness plots for Ken
  • isp processing
    • sorted out ppImage/psastro problems
    • working on automated nightly processing of isp data

Bill Giebink

  • Continued working through PS2 AC controller settings
  • Ordered more DNSM parts (hydraulic fluid, hard drives, etc.)
  • Corrected ipp037 RAID card wiring

Roy Henderson

  • PSPS
    • Bulk of work was finishing new FITS -> CSV code for the DXLayer.
    • Real data successfully loaded on sandbox with new schema
    • Helped Sue work through an ODM bug on the Maui cluster
    • Began design of recovery system with Conrad
  • IPP
    • IPP processing training camp with Chris and Heather
    • Wrote wiki page outlining processing czar duties

Paul Price

  • Sent muggled ThreePi?.20100330 to MOPS
  • Set 3pi self-diffs to 'drop' state
  • Updated ppCoords to take streaks file, and to produce ds9 region files.
  • Investigating magic triggers: lots of "grass".
  • Processing czar
    • Set several tens of failed nightlyscience stacks to 'drop' because input data is ancient and gone.
    • Set LOTS of data to clean
  • Investigating claim of diff photometry not going deep enough
    • Playing with a single chip TTI pair through warp and diff
    • Instrumental detection limits: chip = -6.9 mag, warp = -6.6 mag, diff = -7.4 mag (all should have the same zero point) --> diff is reasonable, compared to chip
    • Worrying about covariances again: something goes missing at warp, which appears to be the covariance.
    • We have a variance map and a covariance "pseudo-matrix" to describe the noise properties, and these two cannot be simply added at the diff stage. Have a solution that could benefit from some simulation to verify.
