News / Meetings / Visitors

  • CALIM this week - Every-other-year meeting that focuses on calibration and imaging. Meeting is telescope agnostic, but is funded by telescopes.
  • RFI Meeting next week.
  • ADASS and Astroinformatics also next week.
  • Cal-I-Am, Sam-I-Am's brother, is in Socorro this week wink

Build, Release

* Release is out, congratulations. * Avoid moving Jira tickets to "Ready to Verify" for now. Use "Ready to Validate" instead. * New build artifacts.

Verification Testing

  • Continued challenges with the ATCA casaguide (
    • The importatca task was importing the rpfits files in different order, depending on platform
    • This was causing a problem in the casaguide, which assumed pre-determined fieldids
    • This has been addressed by updating the guide to spell out which to import the files
    • importatca uses Directory in casacore
    • Alphabetical order in Mac, Debian, and Centos - not the case in Redhat
  • Reorder the numbering of the tests, to better reflect the tags for the tests and to allow scalability of the increasing number of tests (now using 4 digits instead of 3, unit tests before regression, etc)
    • In general - low numbers are calibration, high numbers imaging, higher numbers regression tests
    • Akeem and Ville coordinated on this

Validation Testing

  • Working to clarify which tickets need verification vs. validation. Jen, Anand, Jeff, need to meet on this.
  • Tclean casaguides are ready.
  • Update bug workflow to add under verification to resolved transition.



  • Benchmarking tests on parallelized tasks
    • Changes to allow pipeline to run in parallel is waiting on Ger.
  • preparing ADASS presentation
  • AIPSRC variables specify how much memory should be used. Jeff wants to know where these are respected and where they are not.


  • CASA 5.0 Planning, please fill out your development calendar.
  • Documentation


  • Recommendation for Cycle 4 sent to JAO, reductions started at NAASC
  • Cycle 5 planning
  • Refactoring for Cycle5 started
  • Lazy filler discussions


  • Doc update meeting today @ 2pm

  • Jeff Kern
    • CASA-5.0 Planning
  • Susan Loveland
  • David Mehringer
    • (CAS-5740) CASA needs equivalent to BLSUM/ISPEC for integrated line flux density: RTT. Fixed inputs bug and added documentation as requested to specflux. Received yet more requirements. At this point, it seems the requirements list is ever expanding, so once these two mods have been verified I'm going to close this ticket and open others for the additional requirements, since the initial implementation was long ago complete.
    • Discussed how to write task and tool docs in plone with Jeff.
    • Learned I will be modifying statwt. Received some pointers to VI/VB docs.
    • (CAS-9129) impv bug. RTT. Fixed. Bug due to image straddling longitude=0.
    • (CAS-9067) improve image history for ia.rename(): RTT. Updated examples in docs as requested.
    • (CAS-9095) fix bugs in image analysis introduced during migration to casacore namespace: Resolved. Fixed.
    • Created a bunch of documentation related tickets for release 5.0.
    • Created a bunch of immath reimplementation tickets for release 5.0.
    • (CAS-9072) listobs contains blank lines when spectral windows are not WVR-corrected: WIP. Pinged Julian for casacore review. Looks like he has merged this morning. Thanks Julian!
    • (CAS-9063) improve image history for ia.continuumsub(). RTT. Added writing fit summary to history as requested.
    • Received Confluence tutorial from Jeff.
    • (CAS-9019) imcollapse doesn't compute some stats correctly for complex-valued images. WIP. Pinged Julian for casacore review. Looks like he has commented on the changes this morning. Thanks Julian!
    • Reassigned several image history tickets to Mark L since he wants region information recorded. Pointed out that regions can be very large dictionaries which will clutter the history (if they are file names, these are written). Asked him if he really wants such large data structures dumped to the history.
