IPP Progress Report for the week 2010.11.08 - 2010.11.12

• Thursday off
• IPP Czar on Tue and Wed
• MOPS Czar (all week but no obs on Thu and Fri)
• Stand-by concerning databases replication (waiting for the replication host)
• Contacted Bill Giebink concerning the test framework. Some stuff is running on ipp002. I didn't have the time to go into the details.
• Tessellation: I got the software/scripts on Tuesday. I ran some experiments on Wednesday and I sent some results that seemed excellent on Wednesday (better N/fov size ratio and smaller inter-cells distance). I spent Friday looking at some references for the problem to figure out if the number of observations could be decreased. Unfortunately, on Friday at 5:30PM, I was told that the metrics that I thought were to be optimized were not the right ones. I will start again on Monday... I'm missing the tool that give the number of observations disks a given point falls in.

• worked on wiki and ken's list. Information on how to modify the sidebar is now on the wiki: ​http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/HowToEditTheTracSidebar
• zeropoints - investigating why 20101108 w band zeropoints are off
  • plots of mag_inst vs mag_inst - mag_ref look very similar for both good and bad sets of exposures
  • tried making histograms of mag_inst and mag_ref to figure out what is bad (didn't work)
  • tried ordering the w band exposure by different columns to see if there was any way to sort on the good/bad zeropoints -sorting by n_stars sort of gets most of the bad exposures (bad ones have fewer stars).
  • transferring smfs for gene to investigate
• met with eric gaidos (skyprobe)
• merged minidvodbs 249-261 for gene's threepi dvodb reconstruction
• investigating skyprobe relphot problems
  • it segfaults when it finds no stars - fixed
  • Using GRID_TOOFEW 0 STARS_TOOFEW 0 causes it not to segfault (but I'm not sure if it is doing anything useful)
• ifaps1 things
  • cleaned up disk space a bit
  • downloading threepi minidvodbs -> /data/ifaps1.0/ps1data/catdirs/ThreePi.Minis/ThreePi
  • answered Tomo's questions
• czar thursday
• off friday

Roy Henderson

• Czartool:
  • improvements to temp file handling (IPP czarpoll was clashing with other users)
  • added stacked histogram rate plot to czartool page
  • stages (chip, cam etc) now ordered properly on all plots
  • auto interval function for rate plots
  • fixed bugs in timeDiff functions
  • while doing metrics (below) added ability to show magic mask for a single exposure
• Metrics:
  • encapsulated day metrics into a class (DayMetrics) that inherits from a new Metrics class handing stuff common to all metrics pages
  • now getting magic mask fraction and plotting

Bill Sweeney

• Reorganized warptool -towarped to avoid very long query time when lots of warp runs are outstanding. The problem was with the way 'order by priority' was implemented.
• Implemented changes to publishing system to allow OSS and 3pi detections to be processed simultaneously.
• Created chip runs for the CNP calibration fields. Rediscovered bug in getting stars reference catalogs near the pole.
• Created new MD04 tessellation MD04.V3 which has pixel size closer to the gpc1 camera. Queued new set of warps for those.
• Studied chip processing in preparation for implementing replicated outputs and better handling of update errors.
• Wrangled some exposures through the system to the rsync server for the outreach program.
• Debugged and repaired more problems with MPIA postage stamp data store. Looks like I my have inadvertently deleted some data files. Now that I understand how the system is configured it will be easier to debug problems in the future.
• Debugged and fixed problem on postage stamp request form.
• One day as official processing czar. Other days was a pest for the acting processing czar. (Fix the faults!)
