    pending a couple of minor fixes:

    • Pending feedback from production tests now.
      • If OK, expect new tarball next week.
      • small recipe change to move the combined continuum image, need to check to see if SSA will pick it up. Also should be added to VLA pipeline webpage.
      Again, should be done early next week
  • QA-related pipeline requests in the "no flagging" era
    • Large image/cube mitigation.

    • Tickets to be created: VLA QA Evaluation criteria
• VLASS
  
  • Planning for VLASS-II
    
    • Now have Texas TACC account set up.
      • Laura will set up meeting to discuss DMS involvement in TACC GPU testing.
      • ML to write plan for DMS needs Plan sent to Jeff for DMS effort request for VLASS-II, including estimated FTEs, schedule etc.
      JHU has available computing, but need to pay cash...
    • 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 ~3". Looks like tests may be working.
      • Validate and profile hpgawp (GPU) pipeline locally (L4s)
        • GPU gridder working in tclean alone, issues with VIP script
      • Get awp2/awphpg into pipeline:

        • Still needs bug fixingWaiting for CASA 6.7.1 branch
      • 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, asked K Scott to install 3-4 for testing.3 installed in nmpost091-093, can run 27 at once in NMTech.
  • Moving VLASS stash data back to lustre and serving it to community from there
    • List of what is where and needs to be copied over on VLASS Product storage
    • (late breaking) on hold for now due to lack of inodes on lustreHave 200TB of space in /lustre/projects/vlass until Feb 2026 (then goes back to 100TB).
  • Ep3  QL catalog - Dillon to write-up paper with catalogs, we will put them on VLASS website.Dillon's median stack QL images now available from the VLASS cache, ML to write eNews article and contact CADC.
  • Steve publishing HIPS to CDS.
    • Will appear in CARTA-5 when registered, should do a joint eNews.
  • New Ep1+2 catalog for SECI masks being testedlook good, implementation:

    Seem OK! Juergen will check with Rui about implementation, might just be a recipe change
  • Calibrator uv ranges - Tierra testing.
  • 2.1 SECIs at end of processing chain to be placed "on ice" (~ 100 images) in case improved calibration can be implemented in CASA by the end of VLASS-II
    • Sergio looking into changing PB limit for some of the diverging ones that converged in QL
    2 SE calibration begun for EBs that need uv-ranges set
    • compressionantexclude - James testing
  • ML and DA(s) to check 3C138 for pol angle changes prior to 4.1.
    • Rick Perley is looking at this too, so we may not need to.
• AOB
  • Cosmic AI call for small (~$30k) proposals, abstracts due next Friday
