How did it go?
Ilse giving CASA/VLBI talk at Radio Camera Initiative Seminar Dec 11 @ 1600 UTC
JIRA (VLBI) Status
(George) CAS-12735: Frequency meta-info (includes generalized fix for CAS-12553, and several other bug tickets)
Continued progress, been distracted by 6.1.1/6.1.2 in recent weeks. Committed to completing it!
(Des) CAS-12765 (wide-spaced spws): waiting for freq meta fix in CAS-12735
(Neal) CAS-13184): accor corrdepflags.
Assigned to Neal for verification blessing.
(Mark) CAS-8537: gain curve. Now in validation. Need to ping Jen.
(Mark) Test of gaincurve to use small dataset recently obtained by Justin: TL015
(Mark) TL015 revealed some importfitsidi bugs fixed in casacore
(Neal) CAS-12736 (revised accor test) Neal updating verificaiton tests with TL015 (found same trouble as Mark on gaincurve)
(Mark) CAS-12989 (eMerlin crosshands) Validation complete (Anita Richards)
Need hard-to-get eMerlin dataset for proper verification test....
(Pam Ford) CAS-11318: Fringe-fitting solution plotting (incl. dispersive term) has been implemented in plotms!
(CAS-13056, CAS-13003, and possibly CAS-13005 to slip to next cycle)
CASA 6.3 prioritization
Justin collating high-priority items (see email dated 2020 Nov 19).
Due first week of January for CASA planning process (there will be a confluence page and JIRA filter, etc.)
Other development topics
(**Mark) Per-scan interpolation
in imported Tsys
CAS-12485: OTF weight munging for solve (Can we complete validation and deploy? Des seeking interested users at JIVE)
(Mark) VLBA pulsar binned data.... requires casacore fix to importfitsidi (PR pending, CAS- ticket pending)
(Mark) Generalized polarization basis conversion
(George/Justin) to coordinate initial testing on CASR-463 (TEC) to better characterize basic requirements (also CAS-13040 re TEC retrieval changes)
