Architecture

• Technical Forums:

HPC

Development

Pipeline

• ALMA observing modes meeting
  • full automation requires public antenna position and flux catalog services
  • for interferometry pipeline emphasis on imaging and science ready data products
  • for single dish pipeline emphasis on commissioning
• CASA 4.3.1 / ALMA interferometry pipeline: ongoing final acceptance testing
• CASA 4.3.1 / EVLA interferometry pipeline: waiting for CASA setjy fixes validation, running in automatic mode
• imaging development
  • NAASC will provide continuum identification and imaging heuristics development support using tclean
  • ARC(s) will test pipeline imaging tasks using Cycle 2 data
• meta support
  • pipeline will work with ALMA archive and group in Italy to auto-generate meta-data

  • ALMA observing modes meeting May 5 - 7
  • testing ALMA pipeline on full polarization data sets
  • ALMA interferometry pipeline error handling improvements for session support
• Pam Ford
  • plotms performance tests when loading cache (CAS-7474)

  • CARTA
    • State Save/Restore Work
    • Remove window caption bars making settings available through menu; make user settings visibility part of state.
• David Mehringer
  • 3 days vacation, 2 days in office
  • Discussions with Mark and Darrell re: getting me an OSX development environment. At some point, the plan was to get me an account on razor so I could VNC there and develop on a machine on which a CASA development environment is actively maintained. But that plan appears to have expired, so it seems I'm back to trying to get a development environment on my old MAC laptop. Step 1 is for IT to upgrade the OS to whatever version CASA supports now. Step 2 as it sounds like is to get Ville to configure/install the third party CASA dependencies since I've wasted far to much time in the past trying in vain to do that. Step 3: Profit.
  • Jeff forwarded me mail from an AIPS list re: possible UVFITS issue. User said he was going to make further inquiries at ASTRON because it might be an underlying casacore issue and said if/when necessary, he would raise the issue with the CASA group. So, at this point I'm waiting and seeing. And since most of the UV FITS code is in casacore and we currently do not have a trunk version of casacore to which I can commit modifications, not much I can do presently anyway.
  • (CAS-7523) MSMetaData::getNetSidedbands() should return actual values from MS: Ger and I started this discussion while I was on vacation and I opened a ticket for it when I came back. After inspecting the code, I have a reasonable solution, which I cannot implement until I have commit rights to casacore trunk.
  • (CAS-7499) ia tool used in imstat online help examples: Updated ages old doc example to use imstat rather than ia.statistics().
  • (CAS-7485) Modify SubImageFactory interface: created interface so extra cloneII() step is no longer necessary and cleaned up implementations. Modified callers and removed now unnecessary code. Awaiting commit rights to trunk casacore to clean up remaining bits.
  • (CAS-7268) importuvfits creates inconsistent MS: Modified ms_cmpt::from_fits() and python task wrapper to be more consistent with current exception throwing patterns so that message priority is correctly tagged as SEVERE.
  • Attended PMD talk.
• George Moellenbrock
  • CAS-7478: added sanity check on spw and fitspw parameters (checkin on release branch pending)
  • Personal build maintenance
  • Attended parts of ALMA ObsMode meeting
  • Investigating parametrized (e.g., antpos) solutions in cal library.
• Dirk Petry
  • worked on tests to judge impact of Boost differences between OSX and RHEL for wvrgcal
  • CAS-7270 and ICT-3873: work on ephemeris handling in importasdm; nearly done; should still go into the 4.4 release
• Martin Pokorny
  • Added parallelizable iteration control at C++ layer to new prototype tclean -- all components in the new framework are complete. Started on design report to send around for comments.
• Urvashi Rao
  • Continued making functional test programs for tclean (with detailed failure messages to aid debugging).
  • Some user support and email discussions.
• Darrell Schiebel
• Ville Suoranta
  • Light at end of tunnel on importasdm
• Julian Taylor
• Takahiro Tsutsumi
  • Added setjy workaround for CAS-6463 (force to set fluxdensity=-1 internally)
  • tClean zero rest frequency handling CAS-7490 (fixed for cube as well as mfs case)
  • Started to rework on Stokes Q/U/V image bug (CAS-7362) in tClean to be ready for check-in
