News / Management
  • Congratulations Jan-Willem on Assistant Scientist appointment
  • Congratulations Pam and Kumar on Star awards
  • Kana leaving NRAO in October - Joe Masters will be new Pipeline Lead
  • CNGI Framework Trade Study Report - this week
  • CASA 6 Initial Release - Documentation, examples, tutorial development


  • Calibration and Flagging
    • N/A
  • Imaging
    • Issues found by recent ALMA tests :
      • CAS-12433/CAS-12432 : Issues at freq-chunk edges. In validation
      • CAS-12550 : perchanweightdensity=False (i.e. old behaviour) is ok in 5.4 but seg-faults sometimes for 5.5/5.6. (pending)
      • PIPE-375 : 'inf' restoring beams from stripy PSFs. CAS-12559 fixed one part. Script provided to pipeline team for heuristics if needed. In validation.
      • PIPE-387 : Efforts ongoing to reproduce error. Only CB can still make it fail.
    • CASA 5.6 dev items
      • ARD-25 / CAS-12563 : In Validation. [ pointing corrections for VLASS + bug fixes + tests ]: VLASS tests (validation) are OK. mem bugs fixed and functional verification tests pass. ALMA test passed.
      • CAS-9621 : scalebias for mtmfs + improvement for multiscale (validation and bug fix)
  • Data Visualization
    • CAS-12408/12457 : Plotms fixes ( PR issued )
  • Import / Export
    • N/A
  • Infrastructure
    • N/A
  • Simulation
    • N/A
  • CASA 6
    • There is a new blocker for running tclean in parallel under CASA6. imageconcat is a requirements for tclean running in parallel, as it uses its binary to produce the concatenated images.

Build / Testing

  • Infrastructure
    • N/A
  • Unit
    • N/A
  • Verification
    • cas-12424 : Test framework code ready for python 2.7 and also working with Tom Booth's first ALMA stakeholder test.
    • The automated tests keep reporting a failure in "pipelineTest_vla". Who/what ? Brian Kent
    • Working on test cases for replacement tasks for uvcontsub
  • Validation
    • 5.6 validation list:
        • CAS-12433 tclean with chunks has discrepant PB, restoringbeam, and spectrum at edges of subimages, branch needs merge from master to include CAS-12434 fix
        • CAS-12457 plotms axis range issues (parent ticket for four sub-tickets), one more build coming with fix to plotms crash
        • CAS-12493 Extend fringefit calibration table to make space for a dispersive term
        • CAS-12485 Add options for weighting in fringe fitter least-squares solver
        • CAS-9621 tclean : Improvements to Multiscale CLEAN and add 'scalebias' option to MTMFS CLEAN, testing report back on Friday and needs attention
        • CAS-12545 Fix some of the importvla bugs identified in CASR-416, needs some validation, requested by Juergen/Nick Ferraro (?)
        • CAS-6747 calculate/transfer bandpass solutions in RF and IF space
        • ARD-25 / CAS-12563 AWProject ticket, what is the status of VLASS testing?
        • CAS-11552 variable nchan w/ combine='spw' in gaincal, likely to need more extensive testing than just bug fix testing

        • CAS-12148 Serious issue with explicit setting of restoringbeam parameter in tclean
        • CAS-12528 Add CalAntennaSolution changes to ASDM code as requested by the VLA
        • CAS-9108 Linear basis-specific 'Xf' (multi-scan) improvements
        • CAS-9106 Migrate qufromgain (python) to gaincal
        • CAS-12495 image sideband atmospheric curve in plotms

        • CAS-12395 makePSF in hifa_imageprecheck unacceptably slow - implementation of rectangular convolution function -- currently in verification, but I assume PLWG wants this in 5.6; pinged ticket (maybe not going in for 5.6 after all?)
        • Wideband mosaic commissioning: CAS-11191, CAS-12220, CAS-12223 (others?) --> to 5.7
        • CAS-12550 segfault when perchanweightdensity=False for mosaic dataset
        • PIPE-387 (?)

Single Dish Development (7/11/19)

  • Wataru Kawasaki
  • Takeshi Nakazato
    • Investigation on unexpected test result of CAS-8418 (with Sumi)
    • Test of code review tool (not for pull request but for the review based on commits)
  • Renaud Miel
    • CAS-12084 Plotms Pointings Plot Enhancements: RESOLVED
      • Validation complete, pull request issued
      • Bamboo Tests: CASA PR Build ongoing
  • Suminori Nishie
    • CAS-8418Higher order poinitng interpolation
      • Unexpected value in caluculated result.
      • Investigated and found a problem in specific direction data in pointing table.
      • Revised the PDCalc code, obtained normal result. Further examining/inspecting detail mathematical behavior in cubic-spline
    • low-priority and/or long-term issues was transferred to CAS-12510
  • Obtaining higher C++skills, (OOD/OOP) , tryng to obtain higher-level coding style instructed by Takeshi.
