Current Tasks for the IPP Team

(Up to Main Page)

KPAT / DRAVG Priority Issues (+ Notes)

• latency
  • we have performed a throughput demonstration which meets requirements.

• magic masking
  • the latest large-scale run had a median streak count of 8.
  • we need to make an assessment of the current state of masking by masking bit (both warp and chip)

• stacking: noise correlation
  • we believe this has been addressed by Paul's recent work
  • we need to create a set of examples for evaluation.
  • This is a high priority for this week (2009.11.09)
  • Nigel is concerned about the photometry of psfs in the stacks

• diff images: residuals and noise correlation
  • we have made some good progress on this with the dual convolution technique, and will generate a set of test images this week.
  • another significant source of residuals comes from poor astrometry
  • we also also working on improving the quality of the detection analysis and the associated photometry in the diff images

• astrometry: some catastrophic failures (offsets>3")
  • some progress made in some extreme fields (M42). this may also result in improvements in other poor situations. otherwise under investigation.

• xtalk artifacts.
  • for the near term, we will address this by masking the worst offenders in the camera masking stage.
  • still need to pin down the xtalk rules, but we can implement the xtalk we know.

• other image artifacts.

Other Near-Term Goals

• address warp failures (photometry problem on 3 warps in throughput test)
• someone needs to put together code that feeds back quality info to summit

Eugene Magnier

• psphot & difference images
• flat-field correction
  • run more flattests
• zero points -- use 'blue edge' and full camera
• extended sources
  • set upper limits on Petrosian radii
  • make sure new structures are linked into output functions
  • generate a more complete test set & run tests
• minor ippMonitor & DVO issues
• more data organization work on Manoa & MHPCC clusters
• ingest giebink stuff into svn trunk

Heather Flewelling

• MD08 (& other MD) stacks
• more magic evaluation
• megacam -> nebulous
• simtest work (consistency, etc)
• sdss photometry comparison (start with flat-field correction tests)

Bill Giebink

• DIMM work
• psLib & psModules test code
• build a "realtest"

Paul Price

• check stack code to trunk
• run dual-diffs tests
• examine other pending tasks

Bill Sweeney

• distribution
  • cleanup
  • add label ability to client
• pstamp
  • select different data products
  • cleaned runs (need to fix labeling for update issues)
  • enhance web interface with new features

Chris Waters

• xtalk implementation
• data quality feedback to OTIS
• nebulous
  • unavailable instances errors still outstanding
  • replicate bug & random machine replication
• assessment of stacking detection limits

Natalia Primak

• simtest input / output consistency checks
• simtest visualizations

Cindy Giebink & Steph Mohr

• ready to turn on replication of gpc1, with some research
• memory tests
• memory swaps on ipp005, etc.
