Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
    • CAS-5833: looked into mscal and MSInterface as possible solutions for applying selections in the SYSPOWER table. Sanjay is also looking into this.
    • Added a patch flagdata's parser for input lists to support another exceptional use-case in flagdata. (CAS-6553).
    • Justo and I found problems in mstransform when the input is an MMS (CAS-6543). We need to tackle these problems soon.
    • Building and running tests on release-4_2_2 in linux and OSX.
    • Many non-CASA meetings.
  • Lindsey Davis
  • Kumar Golap
  • Justo Gonz├ílez Villalba
    • Prepared and ran a parallel version of CASA vs AIPS test using SCO Lustre cluster. Produced report to highlight performance gain and scaling.
    • Keep preparing "Installation and advance user guide" for the MPI-based parallel processing framework. I have 75% ready (16/25 pages). I hope to finish before Thursday presentation.
    • Discussed mstransform parallelization and partition issues with Sandra (CAS-6543). After MPI documentation release we plan to focus on fixing these problems.
  • Jim Jacobs
  • Jeff Kern
    • Attempting to get job opening posted
    • Prepared slides for User Committee Meeting
    • Contribution to ICT SPIE Paper
  • Susan Loveland: Worked on integrating new PixelValueManipulator into Profiler with Dave's help; worked on CARTA UI prototype.
  • David Mehringer:
    • Iterated with Susan on integrating PIxelValueManipulator into the profiler, tried to understand the intent of some strange functions currently used by the profile/ImageAnalysis::getFreqProfile() (CAS-6354);
    • added support for complex-valued images to ia.fromarray() for Sanjay et al. (CAS-6510);
    • implemented msmd.namesforspw() (CAS-6459);
    • investigated CAS-6496 and concluded imfit was behaving as designed and documented in this case, but handed back to reporter in case they wanted to make further comments;
    • looked at AipsIO::getNextType() exception context in response to Justo's casa-staff question and reported my findings
    • fixed CAS-6497, newestimates file not being written by imfit;
    • responded off-list to Jeff's memory leaks query to casa-staff;
    • fixed bug causing test_imcontsub to segfault;
    • began groundwork for reporting spw center frequencies in listobs (CAS-6484)
  • George Moellenbrock
    • Summer School Calibration lecture prep and delivery, plus various discussions with students
    • Summer School tutorials
    • (Urgent) Analysis of weight/sigma handling in split; Dirk and I will be sorting this out in the coming week
  • Dirk Petry
    • discussed weights with George
    • discussed integration of almawvr code into CASA codebase with Scott (code will be put into 3rd party part of repository)
    • some tests on the CASA 4.2.2 branch
    • started work on FITSIDI filler extension
    • (for brevity, I will not list work here which is not directly CASA-related)
  • Scott Rankin
  • Urvashi Rao
    • Added support for NCP image projection in (new) imager, as a special case of SIN. This is for ATCA, requested and tested by Mark Wieringa.
    • Attended several synthesis imaging school lectures, lots of user support via tutorials and independent requests.
  • Darrell Schiebel: worked on DBus VO Client (fixed laptop sleep/awake crashes), spent a lot of time trying to build gfortran for a clean install of OSX 10.8 (still not quite there)
  • Rob Selina
    • (On vacation last week)
  • Takahiro Tsutsumi
    • CAS-6530 : wrote a method to concatenate componentlist for multiple spws and modified existing code to work with it.
    • Vacation: 5/15-5/19
Friday NAOJ Meeting
  • Kanako Sugimoto
    • Finalized the plan of CASA 4.3 developments
    • CASA 4.2.2 review & CASA 4.3 kickoff meeting
    • Review of new unit tests of SD tasks implemented during CASA 4.2.2. cycle. Gave feed back to Takeshi and Wataru.
    • Vacation (next week): May 19th - 21st
  • Wataru Kawasaki
    • modified unit tests for sdgrid and sdplot
    • fixed a bug in sd.scantable.sub_baseline()
    • found a minor bug in sd.plotter. reported it to Kana.
  • Takeshi Nakazato: Fixed sdcal2 unit test failure, spent most working time for pipeline development
  • Shinnosuke Kawakami: code reading of ( about IPython MultiEngineClient system) and ipython-doc of

Build, Release, Testing

  • CASA 4.2.1 Released publicly.
    • Outstanding issue from Remy will be pushed to 4.2.2
    • Helpdesk reported a similar issue to Remy's, so we may want to add this to the list of known issues.
    • Switch implemented for QA2 in ALMA.
  • CASA 4.2.2 Merging, Testing, etc
    • George tidying up split and related tasks finalizing the weights implementation. Will work with Dirk on this while here this week.
    • OSX 10.7 and 10.8 will be officially supported (not 10.9).
    • RHEL pre-release package is priority over OSX at this point. Will split the package release as we did for 4.2.0/4.2.1.
    • Scott working on merging the changes committed to trunk. The build works on RHEL but fails on OSX at the moment.
    • George working on a developer build to verify weights changes in isolation. Scott may have asked a few other developers to test commits in isolation.
  • Archive retrieval version of CASA for the VLA - IERS table in repository
  • Trunk build tested last week (including weights) by Crystal and others.
    • Darrell prepared a developer build to see the changes in the weights implementation.
    • Extended testing on the 4.2.2 pre-release packages.


  • Technical Forums: Justo, MPI, Thursday 5/22. Justo working with helpdesk to connect to presentation remotely. Justo sent URL to Jim and Jeff to test the presentation.
    • 6/5 - (Need a Volunteer)
    • 6/19 - ESO Holiday


  • CASA 4.3 progress.
  • Items requiring clarification


  • N/A


  • Dirk - presentation this Friday by Jim? Need to confirm, likely at 2pm or 1:30pm. To be confirmed.
  • 10.9 support - Juergen has people testing the 4.2.1 OSX release on 10.9. George will test the release on his new laptop.
