News / Meetings / Visitors

  • CUC Face to face
  • Jira Move
  • CASA Face to Face
  • Documentation

Build, Release

  • pCASA test started failing, time to remove the deprecated simplecluster?
  • Mac builds now running on virtual machines

Verification Testing

Validation Testing

  • trying to clean up old/4.7 tickets prior to the release and move to new testing system... thanks for your help in closing tickets
  • testing of imstat (thanks Dave) and plotms average bin plotting (thanks Pam) are converging
  • FEED table tickets (CAS-8799, CAS-8477, CAS-4885) testing still ongoing... how important is SPW information in the FEED table?
  • uvcontsub (vs uvcontsub3, vs mstransform-uvcontsub) testing

Architecture

  • Warnings Summary
  • Move to casacore namespace will happen today. There may be a few build glitches as part of the process.

HPC

Development

Pipeline

  • Pipeline C4R2.1 branch created. This is the branch that will distributed with CASA 4.7
  • Issues
    • Moving object imaging with multiple ms(s), ephemeris tables, tclean, without concatenating
      • Status of movingsource parameter in imager tool defineimage method
    • tclean divergence criteria
    • Stuck executions, out of bounds error ?
  • Lots of test data set issues

AOB

Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
  • Lindsey Davis
    • Responded to testing email
    • Fixed various logging and plotting bugs
    • Drafted newsletter article
    • Branched pipeline for C4R2.1
    • Completed release notes for pipeline C4R2.1
  • Pam Ford
    • CAS-8018 - further work on displaying/labeling averaged data
    • CAS-8283 - replace MSSelector with MSSelection/VIVB2 in MSContinuumSubtractor
  • Kumar Golap
  • Justo Gonz├ílez Villalba
  • Jim Jacobs
    • Helped debug CARTA web problem.
  • Jeff Kern
  • Susan Loveland
    • CARTA
      • Region Work (client-side drawing code replaced by server-side drawing code, work on missing models)
      • Fixed 3 segfaults
      • Miscellaneous selenium testing and bug fixing.
  • David Mehringer
    • (CAS-8963) investigate imstat performance issues: WIP
    • (CAS-6896) immath should give control over file used for header generation: IR. Discussion re: default behavior of imagemd parameter
    • (CAS-8964) default value of imagemd need to be clarified: IR. Reiterated why I think the default behavior as immath has done in the past is appropriate.
    • (CAS-5740) CASA needs equivalent to BLSUM/ISPEC for integrated line flux density: RTT. Fixed bug related to multiple beams.
    • (CAS-8943) immath makes and deletes temporary file in working directory that collides with immath from other casa runs: Resolved. Modified temporary name to include process ID so only temp files associated with a given process will be deleted.
    • (CAS-8783) add parallel support to imstat/ia.statistics(). RTT. Fixed a couple of bugs related to fit to half stats. Investigating performance issue associated with images with masks.
    • (CAS-8901) msmd needs a feature to retrieve spw IDs from spw names: RTT. Implemented msmd.namestospws().
    • (CAS-8949) ia.statistics cannot handle concatenated cubes: WIP. Issue with specifying concat image in LEL because CASA opens these in a non-standard way compared to casacore. Ultimately punted to Kumar since I wasn't involved in the design on how this works. Some communication between Ger and Kumar.
    • (CAS-5568) 1 pixel width centerbox does not produce the expected region: Resolved. Caused by machine precision issues.
    • (CAS-8230) ia.pad() will exhaust memory for large images: Resolved. Fixed.
  • George Moellenbrock
  • Dirk Petry
  • Martin Pokorny
  • Urvashi Rao
  • Darrell Schiebel
  • Ville Suoranta
    • Mac builds on virtual machines
    • Carta builds "semi-automated"
    • Helping ACDC with Carta builds

    • No progress this week due to ea-arc server hardware failure
    • CAS-8082 Next steps:
      • Header Items data structure prototyping (ongoing)
      • Define implementation sub-tasks and validate with Pam
