News / Meetings / Visitors

  • Face to Face meeting planning - Feb 24th in Charlottesville
  • Build/Test Process Reviews

Development

  • 5.2
    • CAS-10849 : restoring beam in refconcat images : Fixed in CASA. Ready to validate (via tests by the pipeline group?). Code is currently only on the ticket branch.
    • Refconcat access speed issue that had a fix from KG -- any update from Ger on whether this can go in and when ?

Pipeline

  • 5.1 / Pipeline
    • Dirk M investigating VLA / VLASS restoring beam computation issue
  • 5.2 / Pipeline
    • Dirk M. to implement pipeline part of CAS-10849 fix and test
  • 5.3 / Pipeline
    • Pipeline sessions branch merged to pipeline trunk
      • Includes HPC improvements, major changes to pipeline inputs parameter handling
    • Resumed normal pipeline development on trunk

HPC

Users

  • Viewer tickets: in November, 22% of NRAO-helpdesk tickets related to viewer/plotms (in Aug-Oct this was 15%). For ALMA helpdesk this is much less. Will make an more detailed overview for next week.
  • Documentation updates ongoing: CASA webpages, ALMA CASA Guides (Rachel Friesen), CASA Docs
  • CASA promotion at AAS in Jan (flyer) and EWASS in April (talk Dirk Petry)

Build, Release

Verification Testing

  • PEP + Short Thanksgiving Week = nothing to report here

Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
  • Sandra Castro
  • Lindsey Davis
    • Pipeline sessions branch merge testing, found major new inputs handling error
    • AQUA report presentation to the JVLA pipeline coordination meeting
    • Email discussions on ALMA dbservice, archive connection, Cycle 6, etc issues
  • Bjorn Emonts
  • Pam Ford
    • plotting cal tables in plotms: CAS-8270 under validation for minor bugfixes, CAS-10900 for printing summary to log (a la MSSummary) under development
  • Enrique Garcia
    • Working on CAS-10458: Vi/VB2 vb->visCubeCorrected() segfaults if no column. Improving unit tests on VI/VB2 while at that.
  • Bob Garwood
    • CAS-10644 : skipping duplicates in DATA and POINTING. The POINTING fix has been validated. Still working on the DATA changes.
    • CAS-10939 - importasdm error, exit code 256, Not a bug, closed (no data of the requested type existed in that ASDM).
    • CAS-10386 - Add new shared ALMA code to support 2 new ASDM tables in asdm2MS. The code has been copied to my sandbox and I've verified that test_importasdm still passes. Working on some example ASDMs from the VLA (pulsar table) to use to check this. Possibly also an ALMA ASDM with the new telcal-related table in it. There's a hint in the e-mail comments from the VLA that getting pulsar data to fill correctly may require additional asdm2MS changes.
    • importasdm (asdm2MS) silently skips Main rows when the binary file pointed to in that row is missing. Jeff remembers this as being a feature, not a bug. It may be time to reopen discussion on what should happen in that case. I'm still verifying that this is what happens.
  • Kumar Golap
  • David Mehringer
  • George Moellenbrock
  • Dirk Petry (cannot attend this time due to travel)
    • Problem detected last week in Measures table repository: updates didn't arrive at the repository. (This was detected by the automatic test cron job here at ESO.)
    • Multiple causes, partially masking each other: (1) accidental commit of older version by Tak replaced newer version, (2) power cut as ASTRON prevented update for one week, (3) server ("catapult") setup problem at NRAO
    • Communicated with Darrell who performed various fixes in the repository and elsewhere.
    • The automatic update system at ESO has been reset.
    • As of 26 Nov, ca. 15:00 h UT, all is fine again (both updates via update-data and direct rsync give the desired result; automatic update of this morning went fine; latest version of IERSpredict is 26 Nov 2017, available from the repo)
  • Martin Pokorny
  • Federico M Pouzols
  • Urvashi Rao
  • Darrell Schiebel
    • finished port of CASAtools to OS X
    • added Python 3.6 support to CASAtools
    • spent most of the end of the week understanding the /home/casa mirroring issues at the AOC
  • Ville Suoranta
  • Takahiro Tsutsumi
    • Added unit tests for cube tclean for an MS with a decreasing frequency order (CAS-10940). Also updated ‘Spectral Imaging” section in the plone documentation describing output cube image channel ordering for default width.
    • Discussion on possible use of the JPL-Horizons ephemeris tables in data/ephemerides/JPL-Horizons for ALMA control with Ralph. They will need much higher time sampling.
    • Removed limb-darkened disk model from cl tool’s model option as the current implementation will not work for directly creating image from the componentlist (CAS-10903)
Friday NAOJ Meeting
  • Kanako Sugimoto
  • Wataru Kawasaki
  • Takeshi Nakazato
  • Renaud Miel
