Other admin?
Urvashi now interim CASA Group Lead
NRAO DMS re-org also underway, including managing a few other departures/transitions
George to meet with Urvashi (Apr 21) to discuss general calibration development for 6.5, including work distribution for George, Neal, Jorge Lopez (CV), Victor Desouza (NM, ~June)
(Mark, CAS-13266) Per-scan interpolation via overloading per-obs mechanism. (6.5.0)
(George) Missing calibration (per obs/scan/field/spw/ant) report revision in progress (report missing cal in data iteration rather than trying to predict).
(Des, CAS-13361) Polarization combination for fringefit. (6.5.0)
Awaiting validation
(Des, CAS-13718) Turn on uvrange parameter in fringefit (6.5.0)
Awaiting validation
(Des, CAS-12765) Efficiently combine widely-spaced spws in fringefit (6.5.0)
In validation (Janssen), probably combine with CAS-13266, possibly also with CAS-13361 and CAS-13718
(Mark, CAS-13700) Nant>255 in UVFITS export/import (6.5.0)
Needs validation at NRAO for AIPS compatibility (also miriad?)... George to discuss with Josh.
(Mark) Phase-cal measurements in MeasurementSet
Mark has circulated a new proposed definition for MS PHASE_CAL subtable for phase-cal data to VLBA for comments
Comments from VLBA needed, as that is main customer.
PCAL implementation probably first task for Victor Desouza (June+)
CAS-12485: OTF weight munging for solve (Can we complete validation and deploy? Maybe some interest at VLA in context of 6.5 planning (would need some generalization Des' code)?
Review by George started; probably need to better isolate from existing iteration infrastructure
Exploring prospects for a more general VI2-based implementation that would permit this flexibility in all calibration. E.g., concurrent accumulation of overlapping solution intervals within time-averaging VI2 layer....
Planning for 6.5...
(Mark, CAS-13003). EOP update (6.5)
(George/Justin) CASR-463 (TEC) Need to follow-up on Justin's initial testing, which indicated edge (near-horizon) effects, spurious but cosmetic VLA-specificity, scientific differences in details? (Also some MeerKAT testing, via Bietenholz?) From recent helpdesk ticket: VLBI TEC work should include making it work for single- and dual-parallel hand operation (dispersive delay only), not just full-polarization context.
