CAS-12192, bug specific to fringe-fit solutions, but related to polarization-dependent flagging (CAS-695)
CAS-9965: UVFITs export documentation: GC, TY exporte not yet supported?
Confirmed, but thought not urgent to introduce this support, since these relate to early calibration steps now possible in CASA
"perscan" interpolation options (Mark)
Relevant when linear interpolation over-flags data due to flagged solutions in isolated scans.
Adds a dimension to the calibration "patch panel" mechanism within the calibration apply infrastructure, rather like existing 'perobs' constraint. Has been previously discussed, but this granularity not thought important until now.
George to investigate prospects further, likely only in callibrary infrastructure
RINGS-related issues (Mark)
Extremely wide bandwidth support, including not-fully sampled
Dispersive delay solutions
Items to push for CASA 5.6/6.1 development
(George) Look into correlation-dependent flagging issue (CAS-695)
Keen to abandon "workshop branch" (CAS-10684) when this (and user control of convergence iteration) disposed of
(Mark/Des) Any residuals from 5.5 work (rereferencing, convergence criterion, alternate refant, digital corrections)?
(Walter) Advanced VLBA Amplitude calibration a la Walter memo from a few years ago
Bandpass normalization flexibility: voltage vs. power
accor solutions applied to ACs? (should already be true, else a bug)
(Des) Baseline stacking
(Des) Wide bandwidth and dispersive (see above)
(George) perscan interpolation option (see above)
(Mark) Some items may emerge from Mark's requirements collation process.
Verification testing: Mark asks for template or examples
Neal will provide link to existing tests in the CASA 6 repository (where verification test focus lies)
CASA User Committee encourages "investing in making CASA fully VLBI-capable and securing resources to maintain this capability for the longer term" in the context of the VLBA's return to NRAO management and SRDP.
This recommendation occurs in "External Contributions" section; probably is designed to prompt a more direct resource commitment from NRAO.
