(Ryan) CNGI Status:
Anything to report?
FYI: CNGI Development
Pending admin issues

Meetings/workshops of relevance
CASA User Committee: 2020 Oct 20-23 (virtual)
Committee encouraged by VLBI efforts, including commitment by NRAO to seek additional development funding for VLBA. Need fringefit plotting for CASA6!
Aggregate cal plotting... (Bietenholz)
JIVE VLBI Workshop 2020 Nov 2-6. (virtual)
JIRA (VLBI) Status
(George) CAS-12735: Frequency meta-info (includes generalized fix for CAS-12553, and several other bug tickets)
Making 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
(Mark) CAS-13184): accor corrdepflags. Ready for verification w/ Neal
(Mark) CAS-8537: gain curve. Now in validation.
(Mark) Test of gaincurve to use small dataset recently obtained by Justin: TL015
(George, Mark?) CAS-12736 (revised accor test) Mark may be able to help with test deployment (cf gaincurve above)
George remains curious about OSX version discrepancies; cf 6.1.1/6.1.2 inve
(Mark) CAS-12989 (eMerlin crosshands) Validation complete (Anita Richards)? Need hard-to-get eMerlin dataset for proper verification test.
CAS-12485: OTF weight munging for solve (Can we complete validation and deploy? Des seeking interested users at JIVE)
(Mark) VLBA pulsar binned data
(Mark) Generalized polarization basis conversion
George to study what is needed in plotms for fringefit (CASR-537; may not require significant effort from Pam)
George/Justin to coordinate initial testing on CASR-463 (TEC) to better characterize basic requirements (also CAS-13040 re TEC retrieval changes)
