Agenda

• News

  • Power outage at DSOC/NMTech Tuesday pm due to windstorm, mostly recovered, but many VLASS-related tests delayed. Nevertheless D-config processing has started.
• Program Administration
• Science Ready Data Products
  
  • AAT4.3.4/WS2.8.7/VLASS 2.4.4 deployed
    
    • Enables cal+img, easy to change default workflow processing settings.
      
    • Noted that is only running serial (4-way MPI was requested), not a problem in D-config (in fact may be better in terms of efficiency as cal can only run serial), but may need to fix for A & B configs to prevent overly-long runs.
    • Mitigation may be adequate if implemented, leave at serial for now (more efficient overall).
  • Pipeline CASA 6.6.1-17-pipeline-2024.1.1.22 now installed
    
    • Some hiccups in the cross-site deployment of CASA would have delayed us if power outage hadn't happened... Need improved coordination between SIS and CASA, better communication with NMOps.
    • Discuss with Laura Jensen how this might be improved in future.
  • default recipe for AUDI will try to reapply existing selfcal rather than redo, could handle these as re-runs if needed or do a patch.
    • Decided to rerun pending refactoring of AUDI later this year.
  • QA-related pipeline requests in the "no flagging" era
    • Large image/cube mitigation.

    • Tickets to be created: VLA QA Evaluation criteria
  • Suggest "official" handover of SRDP VLA Ops March 31st. From then, Amy will be responsible for tracking statistics, VLA sections of SRDP webpages, SRDP criteria for VLA data.
    • Maybe write an e-News article - spectral line pipeline, 3C48 back as an SRDP calibrator, transfer to NMOps etc.
    • For next month's enews and focus on user-facing changes.
    • OK to go from "SRDP" to "Quality assessed"
• VLASS
  
  • Planning for VLASS-II
    
    • Now have Texas TACC account set up.
    • Plan sent to Jeff for DMS effort request for VLASS-II, no response yet
    • JHU also interested in an MOU, but need real money.
    • VLASS-II priorities:
      • Validate pipeline for 1" cubes with tapering (SECC)
        • Looked into varying cube plane sizes/pixel scales, not much gain.
        • Testing tapering to ~2-3". 
      • Validate and profile hpgawp (GPU) pipeline locally (L4s)
        • GPU gridder working in tclean alone, issues with VIP script.
          
        • Waiting for 6.7.1 CASA branch so we can get it into the pipeline.

      • Get awphpg running on different GPUs (specifically H100 Grace Hoppers at TACC).
      • VLASS manager changes/data origin setup.
        • K Scott has "read only" version running, need to get products back.
    • 30 GPUs arrived, 3 installed in nmpost091-093, can run 27 at once in NMTech. 
  • Ep3  QL catalog - Dillon to write-up paper with catalogs, we will put them on VLASS website.
  • Steve published HIPS to CDS, should appear in e.g. Aladin, probably ESASky too in a few hours.
    • Will thus appear in CARTA-5 when registered, should do a joint eNews.
  • New Ep1+2 catalog for SECI masks look good, implementation:

  • Calibrator uv ranges - Tierra testing.
  • 2.2 SE calibration begun for EBs that need uv-ranges set
    • compressionantexclude - James testing
  • Rick Perley checking 3C138 for pol angle changes after it flared.
    • Update from Rick: ~2 deg change only
• AOB
