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
  • Ken posted these on the ps1sc wiki: ​http://ps1sc.ifa.hawaii.edu/PS1wiki/index.php/SkyBackground
• 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.
