    • Pipeline review TBD
    • Feedback page comments resolution still owed
  • Development Process updates (beginning with 5.4)
    • CASR project for requirements management
    • CAS project for development only
      • Planning to reduce number of ticket types
      • Planning to reduce number of stages in ticket workflow
    • Confluence Cleanup
      • High level work tracking of release cycles (next evolution from 5.3 page)
      • Designs and working data for longer term development items (looking at Creately plugin)
  • Confluence Calendar Cleanup



  • Pipeline F2F likely to be May 7~11
  • CASA 5.1 / Pipeline
    • Complete
  • CASA 5.2 / Pipeline / HPC
    • Complete
  • CASA 5.3 / Pipeline
    • CASA / Pipeline callibrary integration
      • standard ALMA interferometry use case works
      • issue with undefined / missing calibrations and calflagstrict
    • use of atmospheric plot overlays in plotms waiting in CASA plotms validations
    • plotcal to plotms migration, prototyping in progress
    • support for multi-vis ephemeris images waiting on CASA
  • Pipeline
    • implementing support for multi-vis matching of spws by name rather than id in imaging code
    • support for antenna selection in imaging code, for dealing with mixed array observations
    • single epoch imaging for VLASS


  • CASA 5.2 (prerelease-5.2.0-5)
    • General performance issues fixed - CAS-10794.
    • No issues found with several nodes / many cores.
    • Looks ready. There are open issues for the future:
      • CAS-10857 - "Differences in pipeline runs between serial and parallel (HPC) testing - hif_findcont and hif_makeimages" (tclean weights and findcont sensitivity to parallel/serial differences)
      • Differences in warnings and error messages between serial and parallel runs.
  • 5.3 - Development, bugfixes
    • Discussed the possible solution for the VLA problems with uvcontsub. CAS-10697: uvcontsub does not work in parallel mode with 'combine=spw' - in progress
    • Created CAS-11076: mstransform needs a way to create a normal MS from an MMS


  • New benchmarking-plots CASA lustre/naasc/ serial vs parallel attached
  • Revised CASA website online
  • European Week of Astronomy and Space Science 3-6 April: slot for talk available (D. Petry), but would need volunteer.
