CASA/JIVE VLBI Coordination Meeting

2019 May 29 @ 1400UTC

Logistics

  • Future Meeting dates (usually last Wed of the month):
    • Next meeting: 2019 Jun 26 1400UT? (Mark has conflict?)
    • 2019 Jul 31? (George has conflict)
    • 2019 Aug 28?

General Admin

  • CASA 5.6/6.0
    • CASA 5.6 Confluence page
    • Feature freeze: 2019 Jun 07
      • Public CASA 5.6/6.0 release possible no earlier than mid-July; ALMA/EVLA pipeline release by Oct 1.
    • (Mark) CASA 6 build environment?
      • Non-parallel build process slow/tedious; a fix for this is in the works in CV (Mehringer)
  • EHT-related article planned for next newsletter, expected ~alongside CASA 5.6 pipeline release
  • (Mark) EHT polarization workshop
  • Jay Blanchard now in Socorro, cultivating interest in CASA VLBI (also SRDP)
  • (Ryan) CASA Next Generation Infrastructure
  • Other admin?

Development/Features

  • (Mark) Requirements collation ConsolidatedRequirements
    • Any news?
  • (Mark) New integration branch: CAS-12325
  • Items for CASA 5.6/6.0 development
    • (Des?) Fringe search windows?
    • (George) CASA 6 VLBI task interface verification
      • (Mark) fringefit task: coordinating with Bob Garwood
    • (Mark) Mark fringefit task as non-experimental?
      • Needs unittest/regressiontest
    • (George) Look into correlation-dependent flagging issue (CAS-695)
    • (Des) Dispersive term (5.6)
      • (George) Expand number of parameters in FringeJones table?
        • Backward compatibility ~complicated on ingestion, since FPARAM column not accessed retrieved until table sliced up for interpolation engines
    • (Des) fringefit performance/stability issues traced to neglecting some terms in fit accumulations; now on track to validate for 5.6
    • (Des) Baseline stacking
    • (Des) Wide bandwidth
    • (George) perscan interpolation option? (5.7)
    • (George) consider overlapping solution intervals? (5.7)
    • (Walter) Advanced VLBA Amplitude calibration a la Walker memo from a few years ago
      • Bandpass normalization flexibility: voltage vs. power

Verification/Validation/Documentation

  • (Mark) Testing of fringe fitting with a model... status?
    • Jay confirms confusion about convolution status of model images imported from elsewhere
  • (Mark) Incremental storage manager issues with SIGMA/WEIGHT column? (PR on casacore pending)

AOB?
