News / Meetings / Visitors

  • Completed CASA F2F, very good turnout and discussion
  • Upcoming CARTA F2F in Taiwan 3/27 - 3/29
  • Kana Sugimoto starting soon in Socorro
  • Working to fill CASA developer vacancy - need to assemble interview panel + questions



  • Pipeline face to face meeting at 5/7 - 5/11 at NAOJ
  • CASA 5.3 / 5.4 / Pipeline development planning uncertainties
  • CASA 5.5+ / 6.0 / Pipeline Cycle 7 planning uncertainties including Python 2 to 3 migration
  • New ALMA Cycle 8 pipeline processing "Fire and forget goal'
  • Good progress on CASA Callibrary testing, ALMA IF good, VLA IF problem with antenna correction caltable, single dish issue
  • Development
    • Progress on ALMA Archive / AQUA / Pipeline interface issues, adoption and extension of pipeline manifest
    • Progress on separating the ALMA interferometry pipeline into separate calibration and imaging recipes
    • Some new CASA 5.3 / Pipeline HPC / MMS bugs
    • Migration from plotcal to plotms is complete
    • Progress on web log error reporting
    • Progress on speeding up remote web log viewing


  • 5.3
    • Fix for CAS-11196: "parallel setjy breaks PL", found by Remy while testing parallel pipeline with CASA 5.3.
      • Was making the pipeline fail in parallel mode at an early stage in calibration.
      • After changes in mstool and nrow(), nrow(True) won't produce 0 after a 'NullSelection'. setjy mishandles the error/exception and returns an empty dict which confuses the pipeline.
      • Tidy handling of exceptions requires a small change in casacore.
      • This problem was already caught in the ESO/Jenkins tests of the pipeline back in October and reported in CAS-10818. Another example on how useful it is to have automated tests of the pipeline!! The problem wasn't solved for setjy back then but deferred to 5.3.
    • After fix for CAS-11196, pipeline fails (both serial and parallel) at the beginning of imaging: CAS-11207: pipeline stage 23, hif_mstransform, failing with "KeyError: 'time'" - fixed today by Stewart.
    • Problem found after validation; under investigation. CAS-10697: uvcontsub does not work in parallel mode with 'combine=spw'


Build, Release

Verification Testing

Validation Testing



Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
    • 5.3
      • CAS-10383 found problems during validation. Pending on the implementation of CAS-11209
      • CAS-4888: still open; it's a simple creation of a test using virtual MODEL column, but it is better if the above is fixed before
      • CAS-9950: documentation. In progress
  • Lindsey Davis
    • ALMA observing session definition discussions with ALMA ICT, illegal use of sessions in VLBI observing script forestalled ?
    • Pipeline / Archive / AQUA interface discussions with ALMA ICT, pipeline manifest will be extended and adopted as the interface
    • Followed up on an ALMA restore data problem, caused by missing caltable file, origin of problem mysterious
    • Fixed a bug in pipeline initcli method that caused 'casa --pipeline' to fail in recent 5.3 tarballs
    • Followed up on CASA Callibrary VLA use case testing issues.
    • Followed up on pipeline spw mapping by name problem
    • Started drafting pipeline manifest definition document
    • Participated in CASA F2F
    • Pipeline F2F travel arrangements
  • Bjorn Emonts
  • Pam Ford
  • Enrique Garcia
  • Bob Garwood
    • CASA 5.3
      • CAS-10386 Add new shared ALMA code to support 2 new ASDM tables in asdm2MS. Ready to validate. VLA expects this for 5.3.
      • CAS-10643 importasdm fails at the bdflags2MS step in at least one case. Ready to validate.
      • CAS-10644 Filler needs to detect duplicate (sets of) rows and retain only one copy. Done.
      • CAS-10738 Review the existing Ephemeris handling code in asdm2MS and fix found bugs. Ready to validate.
    • CASA 5.4
      • CAS-10693 remove boost dependency. Nearly finished. (shared ALMA code is done and will be checked in to ALMA/ACS repo shortly).
  • Kumar Golap
  • David Mehringer
  • George Moellenbrock
  • Dirk Petry
  • Martin Pokorny
  • Federico M Pouzols
    • CAS-10768: "Resource Predictor for Imager" - do we include it already in 5.3? With a switch in casarc, disabled by default. Or otherwise it would be very useful early in 5.4, so memory and (detailed) time profiles for tclean can be produced in general pipeline tests.
    • Fixed CAS-11196: parallel setjy breaks PL, fixed issue, now pipeline can run through calibration, but...
    • CAS-11207 "pipeline stage 23, hif_mstransform, failing with "KeyError: 'time'"": issue in pipeline mstransform / tablereader (both serial and parallel modes).
    • Working on test additions and cvel/mstransform tickets: CAS-10635, CAS-10340.
  • Urvashi Rao
  • Darrell Schiebel
  • Ville Suoranta
  • Takahiro Tsutsumi
Friday NAOJ Meeting
  • Kanako Sugimoto
  • Wataru Kawasaki
  • Takeshi Nakazato
    • completed CAS-11055
    • tested plotms's atm transparency overlay using Nobeyama data ( CAS-9053)
    • tested callibrary on single dish usecase ( CAS-10977, CAS-10723)
      • applycal crashed when single dish calibration instruction is included
  • Renaud Miel
