News / Management
  • Welcome Jan-Willem Steeb to CASA team - imaging developer, sitting in ER-211
  • Organizational Announcements
    • Urvashi returning to CASA team and Science Development Lead and Deputy Group Lead
    • Darrell will be Software Engineering lead of CASA Next Generation Infrastructure (CNGI) project
    • Minor Revisions to Development Process and new Roles/Responsibilities Definition
  • Brian G test process review this week - may be making some changes to our testing philosophy


  • Calibration and Flagging
    • Investigated CAS-11910 "flagdata's rflag with time averaging does not flag data". flagdata looks fine. Undersanding flagging with on-the-fly time and or channel averaging can be complicated. Combinations of options can confuse users.
    • CAS-12295 "rflag dictionaries timedev and freqdev" - improvements to documentation and input consistency checking. More error checking and usability improvements: CAS-12294 "Agent flagger: reorganize agent list checks and clarify messages".

  • CASA 6
    • finished work enabling OpenMP
      • unlike CASA 5 the configure now searches through C++11 compilers attempting to find one which supports OpenMP (i.e. GNU), this primarily affects OSX
    • added ability to query for gRPC compile and link flags
      • python -m casatools --grpc-compile
      • python -m casatools --grpc-link
      • python -m casatools --grpc-protoc

Build / Testing

  • Infrastructure

  • Unit
    • N/A
  • Verification
    • Pilot code review for Neal's listobs verification test
      • Scheduled for Thursday @ 11AM MT/1PM ET - George, are you available?
    • blcal test finished
    • Trouble with imdev interp and stretch parameters?
    • Working on getting refimager in parallel mode in to critical tests (run at each pull request)
      • Trying to secure additional hardware resources to accommodate additional test time
      • Working with Takeshi on prioritizing SD tests
      • Updating which tests are run in the test suites, including using telemetry data to see which tasks are used the most
      • We are also thinking about how to include a serial run of refimager during pull requests
  • Validation
    • Under Validation
      • BLOCKER CAS-11191 tclean mosaic gridder should be able to use VLA POINTING table properly averaging over visibility integration time (related to CAS-12223)
      • BLOCKER CAS-9108 Linear basis-specific 'Xf' (multi-scan) improvements (AND SEVERAL RELATED POLARIZATION TICKETS)
      • BLOCKER CAS-12314 CASA 5.4 can not import new ASDMs with schemaVersion="4"
      • BLOCKER CAS-7210 (CAS-4640) Connect imaging weight gridder ( TCLEAN producing arc-like noise patterns when imaging small chunks of data when robust<1 )
      • CAS-8619 Turn im.apparentsens into a CASA task
      • CAS-11460 im.apparentsens to use the regular channel selection syntax
      • CAS-11965 Fix fitspw issue on master
      • CAS-8087 Support plotting pointing direction (R.A.-Dec.) by plotms
      • CAS-12168 L1 and outlier rejection implementation
      • CAS-12205 plotms: unflag operation doesn't work when time average is ON
      • CAS-10593 Make component list prediction with beam use frequency variation
      • CAS-12021 Add re-referencing support to fringefit task
      • CAS-12033 fix doc(...) command so that it always goes to online plone
      • CAS-11988 (CAS-10294) Propagate spectral window subtable across TVIs
      • CAS-11501 connecting the dots for caltables in plotms
      • CAS-11178 fix stand-alone viewer startup on linux
    • Ready to Validate
    • not yet ready to validate but still needed in 5.5: George's two tickets for cal library fixes, CAS-11978, CAS-11140 (and from search of JIRA for 5.5 blockers not above or closed: CAS-12103, CAS-12277, CAS-12237 [which I think is one of George's tickets])
