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?
