All tickets pertaining to VLASS SE operations should have the VLASS-SE-OPS label.  Add VLASS-SE-DISCUSS label if it should be brought up in this meeting


News

  • NSF proposal to assist with VLASS processing in flight, due 1/21/21
  • Testing suggests that mosaic gridder may be sufficient for most of the sky.  Alternatively AWProject with w=1 may be used.  Likely that AWproject with w=32 will be needed for some areas of the sky.  
  • Anticipate acceptance of mosaic imaging by mid-February

Open Issues

  • How to push for requirements for deciding which gridder or imaging parameters to use ?  Need an early heuristic based on some characteristic, e.g. declination, that triggers more complex imaging ?
  • VLASS team will document official mosaic workflow and make available as soon as possible.

Decisions

  • Preference is to have discrete pipelines for preferred gridder or w parameter rather than an early heuristic.

Agenda

Open Issues

  • SE Imaging Workflow: Is the component list generation step in the workflow or does it only run the pipeline
  • How are SE calibration products handled in the VLASS Manager (I'll explain) 
    • Decision on whether to produce a Mosaic implementation (we will produce one)
    • Pipeline available for testing (available for AWP implementation, Mosaic in progress)
    • SSA PIMS workflow validated (validated)
    • SSA SE Imaging workflow ready for testing   (In progress ?)
    • Pipeline validated  (6/10)
    • Pipeline released   (6/10)
    • SSA SE Imaging workflow validated
    • Begin operations (shooting for June 1st 25th)
    • Migrate above to htcondor (Mid/late August)
    • Accept and archive implemented

Decisions

Agenda

  • Pipeline
  • SSA 
    • PIMS testing in progress
    • SE Imaging workflow testing state 
    • HTCondor design
  • SCG
    • Verification of pipeline vs VIP script in mosaic and AWP (AWP is consistent).  Stalled for now
    • Investigation of  GPU gridder vs CASA underway
  • Pipeline
    • Status update
  • SSA
    • Validation progress
  • SCG
    • Wrapping up processing 7 square degrees + 7 repeat  
    • 43 sq degrees complete, 30 running.
    • Can we speed up the import step for the split stage.   SCG will examine where time is spent and suggest improvements
