    • ASTRON/JIVE
      • Science/computing staff continuing work-at-home for now
  • CASA Release Schedule
    • CASA 5.7/6.1: Pre-release package branch July ~27; public release imminent...
      • CASA 6.1.1 for ALMA PL being exercised
      • CASA 6.1.2(/5.7.x?) w/ polcal fix (VLASS, ALMA?) pending
    • CASA 5.8/6.2: Development ongoing.
      • Should be wrapping up development ~now
  • JIRA workflow migration (simplification) complete
    • Some ticket states have evolved (no "sub-tasks")
    • Package build (CASA 6) triggering ("Package" field via ticket "Edit")
    • Refer any issues/problems to George
  • (Mark) Requirements collation status?
    • 2020 May 07 document
    • (George) Should complete re-numbering to better align with prioritization exercise from May 2020
    • (George, Justin) Need to forward Requirements Doc and prioritization to Jen Donovan-Meyer, as input to Stakeholder process for CASA 5.9/6.3
  • (Ryan) CNGI Status:
    • CNGI Study Closeout process (2021+) being prepared, including: prototype demo package of basic flagging, calibration, & imaging; review of C++ code reuse prospects cf demos; concrete ngCASA specification project mapping ngVLA (and retrospective ALMA) requirements, and including a multi-year schedule, staffing plan, etc.
    • FYI: CNGI Development instructions
  • Pending admin issues
    • DIY casa5 tarball build instructions can be found here
    • casa6 build issues: formal instructions for plotms, CASAshell, casa5/6 co-exist, c++ unit tests in casa6
    • (Mark) Google drive packages?
  • Upcoming meetings/workshops of relevance
    • CASA User Committee: 2020 Oct 20-23 (virtual)
    • JIVE VLBI Workshop 2020 Nov 2-6. (virtual)
      • VLBA/NRAO staff being encouraged to attend!
      • (NB: Some polcal modes broken in CASA 5.7...)
  • Other admin?

Development

  • CASA 5.8/6.2:
    • JIRA (VLBI) Status
      • CAS-12736: accor test needs some VLBA data for proper test
        • Will use BA123a, which has been added to DR
      • (Mark) CAS-8537: gain curve
        • ~Finished? (gencal integration ok?!)
        • (concat, mstransform ok?)
      • (George) CAS-12735: Frequency meta-info (includes generalized fix for CAS-12553, and several other bug tickets)
        • Making progress on defining solve context frequency meta info from VisibilityIterator2 services before iteration over solution intervals; nearing deployment
        • Some coordination may be required in fringefit
      • (Mark) CAS-13184): accor corrdepflags
  • Other development
    • CAS-12485: OTF weight munging for solve (validating?)
    • (Mark) Generalized polarization basis conversion
    • Other:
      • George to study what is needed in plotms for fringefit (CASR-537; may not require significant effort from Pam)
      • George/Justin to coordinate initial testing on CASR-463 (TEC) to better characterize basic requirements (also CAS-13040 re TEC retrieval changes)

AOB?
