Verification Datasets meeting
Attendees: Angelo, David, Frossie, Colin, Hsin-Fang, Mario, Zeljko, Francisco, John Swinbank, Lupton, Simon
Notetaker: David
Hsin-Fang:
- nothing on DECam
- probably not working on verification datasets for a while
Colin:
- not much work with actual data
- pass DIA sources to MOPS
- some correlated DIA sources (e.g. diffraction spikes), not sure what to do about it yet, just try MOPS
- False Positive Rates in the LSST Image Differencing Pipeline (http://dmtn-006.lsst.io/en/latest/)
Mario:
- Joachim working on running MOPS
- probably won’t be able to attend these calls as much as in the past
Simon:
- twinkles update:
- running phosim at NIRSC
- long tail in the runtimes, some timing out at 5 days, moon adds a lot to sky brightness
- a dozen or so frames through stack, MWV will look to see if they are reasonable
- run 1, visit per night per any filters that are available, 1200 individual visits, reduce/coadd/forcedphot
- DESC meeting next week, hoping hundreds run through by then, need to fix moon issue
couple of weeks once the moon is fixed, processing through stack quite quick and straightforward
MWV:
- looking at upgrades to validation_drp
- CFHT, DECam, HSC, full focal planes
- ci_hsc now running, almost nightly
- coadd and deep detection on HSC
- starting to process twinkles data, some issues with obs_lsstsim master that he+simon are working on
- Introducing validate_drp: Calculate SRD Key Performance Metrics for an output repository (http://dmtn-008.lsst.io/en/latest/)
Francisco:
- nothing to report on this
- didn’t get time for HiTS for this semester, focus on getting papers out
- stopped working on astrometry issues with image differencing
- polynomial fits as good as using CP WCS
Angelo:
- QA visualization, two tech notes in progress:
- SQUASH QA Database (http://sqr-008.lsst.io/en/latest/)
- SQUASH dashboard prototype (http://sqr-009.lsst.io/en/latest/)
- working on ingesting QA metric results into a database
David:
- was at “Globular Cluster and Galaxy Halos” conference in Netherlands
- rerunning COSMOS with SDSS DR9 reference catalogs to get good magnitude zero points
- discussion about crowded field photometry codes, maybe use DAOPHOT as a stop-gap solution
MWV: looking at Lauren and Paul’s comparison code
