(George) Should complete re-numbering to better align with prioritization exercise from May 2020
(George, Justin) Need to forward Requirements Doc and prioritization to Jen Donovan-Meyer, as input to Stakeholder process for CASA 5.9/6.3
(Ryan) CNGI Status:
In lieu of aborted CoDR, CNGI Study Closeout process (2021+) being prepared, including: prototype demo package of basic flagging, calibration, & imaging; review of C++ code reuse prospects cf demos; concrete ngCASA specification project mapping ngVLA (and retrospective ALMA) requirements, and including a multi-year schedule, staffing plan, etc.
CAS-12736: accor test needs some VLBA data for proper test
43 GHz dataset likely best-demonstrator; may be possible to re-use something from fringefit testing (Justin?)
(George, Justin, Neal) Coordinate identification of VLBA test dataset, and update test
(George) Continue diagnosis of old VLA dataset test failure
CAS-8537: gain curve:
Mark has working implementation
Merge of current casacore to casa trunk urgently needed (like several other general CASA developments), then easy to commit and PR/merge
Adaptations needed in concat, mstransform?
(Mark) Close w/ concat, will consider what might be needed for mstransform
In general, most users should be satisfied with ordinary (sometimes multi-file) importfitsidi fill, and this calibration established early in processing
Caltables use 16 parameters (8 per-pol), so a polynomial of degree 7.
How to integrate into gencal?
(George) Although transparent adaptation of existing mode desirable, adding new gencal mode probably easiest for isolating and managing required calculations on apply
(Mark) Polarization basis conversion
(Mark) To handle mixed basis EVN arrays, adapt Marti-Vidal code to "calibrate" (within CASA calibration infrastructure) to common (circular) basis via cross-hand gain (slight generalization of XJones) + basis conversion (as an ordered calibration term). For now, an experimental effort, orthogonal/non-distruptive to all else and under the radar; when ready to deploy, offer as a CASA task (with requisite testing, etc.)
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)
