Developer Reports

Monday Meeting
  • Sanjay Bhatnagar
    • Continued working on refactoring and parallelizing cfcache generation code for AProjection.
  • Sandra Castro
  • Lindsey Davis
  • Pam Ford
    • Cal Library 4.5
      • Discussions with George about architecture, parser, interfaces
      • Researched Flex/Bison parser and started on prototype for cal library file parser
    • Tested CAS-7390 (virtual model data) - creates default model data but time averaging is incorrect
    • CAS-7601 (correlation type names) tested and resolved, so CAS-7577 (correlation types in Locate) is now RTT
  • Kumar Golap
    • Bugs
      • Alma mosaic core dumping when undersampled pixels used
      • SD imaging tolerance in locating the pointing
      • trying to reproduce a w-projection bug on a 1.7TB data
    • Discussions about mosaic weights etc
  • Justo Gonz├ílez Villalba
    • mstransform tickets fixed:
      • CAS-7488 : Re-index optional columns in SPW sub-table affected by SPW re-indexing (ASSOC_SPW and ASSOC_NATURE)
      • CAS-7149: Drop empty channels of last SPW when separating a SPW into a non-divisor number of channels.
    • mstransform iterator:
      • CAS-7601: Added interface for new correlation selection methods
      • CAS-7390: On-going investigation of why model data is averaged to 0 in AveragingTVI
    • Misc
      • Discussions with SD team on how to transform Weight/Sigma Spectrum using mstransform framework
  • Jim Jacobs
    • See above.
  • Jeff Kern
  • Susan Loveland
    • Viewer
      • CAS-7207: Flux density not working for multiple beam one per channel image (ready to test)
      • CAS-7608: View GUI testing CAS 4.4 Mac 10.10 (ready to test, verified with Pam's help)
      • CAS-7185: Reset rest frequency in viewer to original value (ready to test)
      • CAS-7617: Profiler should post warning rather than segfaulting with single channel fit (ready to test)
    • CARTA: Layout work
  • David Mehringer
    • Responded to Kana re: stats framework query
    • (CAS-7319) MSMD additions: completed adding a couple dozen or so new methods to msmd tool. Cannot commit until casacore freeze has been lifted.
    • (CAS-7040) region manager wbox function can segfault casa: Resolved as won't fix because apparently this bug was serendipitously fixed at some point.
    • (CAS-7584) no random number seed in ia.addnoise() ?: added "seeds" parameter to ia.addnoise(). Cannot commit until casacore freeze has been lifted.
    • (CAS-7207) Flux density not working for multiple beam one per channel image: pointed out that differences between 4.2.2 and current version did not indicate a bug, since the current version now uses the beam in each channel to compute the flux density for that channel whereas the 4.2.2 version used a single beam in the cube to compute approximate flux densities for multi-beam images in the spectral profile tool.
    • [JIRA] (CAS-7257) discrepancy between spectra extracted by imval and by spectral profiler in viewer: passed back to Dirk because I could not reproduce his discrepancy.
    • (CAS-7329) Casacore LatticeHistograms gives a segfault when setting a range outside of data range: Fixed. Cannot commit until casacore freeze has been lifted.
  • George Moellenbrock
    • 4.4 cookbook edits (Cal Lib Appendix, initweights section, TEC section fixes)
    • SD weighting discussions (CAS-7450)
    • Cal Lib parsing discussions w/ Pam
    • Verified plotms freq-plotting fixes (CAS-7491,7460)
    • Progress on parametrized types in Cal Lib (CAS-6130)
    • Science: EVLA circpol obs prep
  • Dirk Petry
  • Martin Pokorny
    • Started rough design for converting visstat and sdstat to new statistics framework and vi/vb2.
    • Wrote up design document describing MPI usage in redesigned tclean, and what requirements the new design would impose on the CASA MPI framework.
  • Urvashi Rao
    • Got normalization sync'd between MosaicFT and AProjectFT by adding missing nx*ny norm and removing fudges from MosaicFT. Made derived version with changes. Finally... we can edit normalization rules in one place and MosFT /AProj, single/multi-term, parallel=T/F all see it.
    • Made the output of MosFT and AProj contain weightimage (.weight) and normalized PB image (.pb) with pb = sqrt(weight)/max(sqrt(weight))
    • Enabled and tested multi-term mosaicing via MosaicFT - this brings wideband mosaic imaging capability for ALMA.
    • Several other minor edits and fixes....
    • Discussions (about weights...) and some user support
  • Darrell Schiebel
  • Ville Suoranta
    • Fighting Mac Package Signing
  • Julian Taylor
  • Takahiro Tsutsumi
    • Made some changes and bug fixes for cube tclean data/image partitioning. Ran a simple cube tclean test in parallel mode but got an error at makePSF stage..
Friday NAOJ Meeting

    • Feedback to Erik's draft of the single dish chapter in casa 4.5 cookbook and reference
    • Averaging weight discussion ( CAS-7450)
    • discussion of visstat extention
  • Wataru Kawasaki
    • applying baseline table in tsdbaseline ( CAS-7002): implementing in the C++ layer.
  • Masaya Kuniyoshi
  • Takeshi Nakazato
    • started to work on CAS-7441 gaussian smoothing task
    • user test on CAS-7446
      • independent bug was found by tester, fixed it on trunk and release branch
