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/](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/](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/](http://sqr-008.lsst.io/en/latest/))
  - SQUASH dashboard prototype ([http://sqr-009.lsst.io/en/latest/](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
