Development/Features

  • (Mark) Requirements collation ConsolidatedRequirements....Any news?
  • VLBI Integration branch: CAS-12325
  • Items for CASA 6.0
    • (Mark) fringefit task: coordinating with Bob Garwood. Ok?
  • Stakeholder inputs for CASA 5.7/6.1 (not sure if this is public)
    • See VLBI section
  • Items for CASA 5.7/6.1 (need CAS tickets for many of the following)
    • (George) Support correlation-dependent flagging, with user option (CAS-695)
    • (Mark) Spectral-line / astrometry support
      • Fringe fitting on a single channel (or multiple channels with delay turned off) (CAS-12553)
      • Spectral window mapping issues (CAS-12591)
      • Updated EOP corrections
    • (Des) Dispersive term solve, including user control and an FFT-based option for estimating the dispersive term.
      • Must exist in code by end of year (funding progress report)
    • (George/Des) Convert CC tables to image or ComponentList for resolved model-setting
    • (Des) CAS-12485? fringefit weighting control
      • Need good use case for testing/validation.
    • (Des) Wide bandwidth
      • Must exist in code by end of year (funding progress report)
    • (Des) Fringefitting single channel case
    • (Des) Baseline stacking
    • (George) Per-scan interpolation option?
    • (George) Overlapping solution intervals?
    • (Walter) Advanced VLBA Amplitude calibration a la Walker memo from a few years ago?
      • Bandpass normalization flexibility: voltage vs. power

Verification/Validation/Documentation

  • (George) CAS-12591: CTPatchedInterp spectral window mapping bug
    • Needs further investigation.... I suspect this requires additional work addressing differing spw populations in MS and CalTable (portability)
  • (Des) Michael Janssen has found a so-far unreproducible bug... Progress?

AOB?
