tClean issue: Issue with find convolution function in mosaic FT
Blocker issue in plotMS
Justo:
Handling of ephemeris file in msTransform - Go
Parameter names changes - Go
Lindsey to send Sandra UID of example where ephemeris is used for flux calibrator.
Architecture
* Technical Forums:
* Testing in in place on trunk, Google Test requires more thought.
HPC
Julian and Justo fixed an ineficiency in flagdata summary mode (actually in VI/VB2), which benefits the SD pipeline; what took 2 minutes to execute now takes 10 seconds.
Julian also suggested a patch to the SD pipeline that improves pieces of the Python code..
* Have been running performance tests using the alma-m100 regression for the next CASA newsletter. The tests use one of the latest casa-pre-release tarballs. The speedup is about 1.4x faster in parallel. This may improve further once tclean is used in the script.
* Have been running performance tests using the alma-m100 regression for the next CASA newsletter. The tests use one of the latest casa-pre-release tarballs. The speedup about 1.35x faster in parallel. This may improve further once tclean is used in the script.
Data import: fixed HISTORY scoring to account for changes in CASA importasdm HISTORY logging
Flagging: fixedto ALMA deterministic flagging statistics (QA0) reporting and scoring, fixed low gain flagging missing caltable handling
Imaging: sorted out model column selection and uvsub handling problems, turned on full cube imaging, followed up on PSF creation errors and memory management isses with the imaging team
Data export: changes to support new image products, especially multi-term images
Continuum region finding: integrated algorithm improvements from Todd into pipeline
JIRA bug report followups, Tsys flagging, web log links

HPC work as described above.
Have noticed that task uvcontsub calls ms.split() internally and we need to decide if we want a similar method in the mstransformer tool now that split will be deprecated.
Lindsey Davis
Model column / uvsub testing with Dirk M, email exchanges with Dirk M, Urvashi
Discussion / emails on tclean memory management with imaging team and Dirk M.
Fixed pipeline HISTORY scoring issue
Tracked down pipeline script generator bug
General testing
Pam Ford
CAS-7831 blocker - asked for more information than "it's not fixed"
CAS-2091 RFI (pm tool resets options when change data selection) - old ticket that I think is no longer an issue
CAS-7875 (glitchy model column when time-averaged) - issue was actually the averaged uvw values used for uvdist and uvrange, reassigned to Jim
CAS-7851 RTT (restart casaplotms process when it crashes without restarting casapy)
CAS-7242 Resolved (do not show axis when "Show X/Y Axis" checkboxes unchecked)
CAS-7878 Resolved - added Dirk's fix to release-4_5 branch
Kumar Golap
Justo González Villalba
Attended ERIS interferometry school
Refactor DDI/SPW/Pol methods of mstransform to avoid inconsistencies reported in CAS-7814/CAS-7841
Fixed sign issue reported in OTF phase shifting applied via plotms
Updated mstransform section in CASA cookbook
Fixed mstransform problem handling ephemerides files
Implemented a generic weight propagation method in mstransform applicable to all linear combination kernels
Jim Jacobs
Jeff Kern * Strategic Staffing Summit * Eduardo Closeout
Susan Loveland
Attended Very Long process management meeting
CARTA
Worked on support for multiple axes
Pan, image crash, and deployment problem bug fixes
David Mehringer
4 days in office, 1 day sick.
Reported imager_cmpt.cc warnings to casa-staff. ms_cmpt.cc also has several compiler warnings.
Reviewed some of Martin's statistics code mods.
[casacore] Remove extraneous call to sqrt() (#233: reviewed Martin's fix at Julian's request.
(CAS-7679) fitting in non-optical mode does not work when restfreq is not set: RTT, added support to specfit-related code for images which have restfreq=0.
(CAS-5104) LCSlicer::toSlice appears to have a defect, Resolved, Not a bug. Due to a misunderstanding I had about an LCSlicer constructor.
(CAS-5597) CRTF doco improvements: Changed to input required as a way to note that I cannot proceed on this ticket until work on CAS-7704 has been resolved.
Attended yet another marathon presentation given by Eduardo. Had to leave at the 95 minute mark.
(CAS-5893) add the ability to write a spectral profile to an ASCII file in the ia tool: RTT. Completed implementation of requested functionality.
(CAS-6112) Specfit output: Input required. Queried requester if functionality added as per CAS-5893 would be sufficient to resolve this ticket.
After prodding CIS, received USB hub for my new mac that I had requested a week prior. Hopefully this week I will have time to install CASA.
(CAS-7778) msmd should have a method to retrieve the effective bandwidth or the effective resolution of the channels rather than only their formal bandwith: RTT, implementation complete.
(CAS-3366) listfile parameter for imstat: RTT, modified output as requested.
(CAS-5996) immath unit- (and beam-) awareness: Began implementing general parser for LEL expressions in order to extract image names using a lot of regex and string manipulations.
(CAS-7637) msmd should have methods to retrieve REST_FREQUENCY and TRANSITION frm the SOURCE table: RTT, completed implementation.
George Moellenbrock
ALMA Polarization testing/discussions w/ Crystal --- fixed (in release) a problem with feed pa discovery triggered by a spw name convention change at ALMA
Cookbook Cal chapter edits for 4.5
Various other user support/testing, most notably a query re spurious solutions from blcal from Robert Laing on a 500000:1 imaging project.
Adapting to RH6 on my dev machine....
Dirk Petry
Martin Pokorny
Submitted pull request to casacore for changes needed for visstat2; later added unit tests for changes, as well.
visstat2 C++ code largely complete; a few MS columns not yet supported; needs work on interface and integration with task layer.
Urvashi Rao
Implemented cube chunking for large cubes via reference subimages.
Tested multi-field across chan ranges and isolated some issues.
Finished inline docs and iterating with CB on edits
Emails about continuum subtraction and model columns
Darrell Schiebel
Ville Suoranta
Julian Taylor
tested new mpi dependencies of casa binary rpms (the rpms with stuff in /usr/bin)
removed unnecessary getFrequency calls from flagdata, factor 10 performance improvement for some summary mode cases
improved performance of visbuffer::getFrequency by removing unnecessary Unit object creations
reduced cost of Unit object creation in casacore
started looking at some timeout issues with sdpipeline, found a couple simple but significant performance improvements
Takahiro Tsutsumi
Added a unit test for setjy for the data with ephemeris table
Updated tclean inline documentation for cube imaging sub-parameters
Parallel cube tclean testing, found an issue (appeared that it was not going through request iterations in minor cycle).
Friday NAOJ Meeting
Kanako Sugimoto
A summary presentation of CASA 4.5 development cycle. Useful feedback from team members. It turned out short testing period by quick release process is making Erik's life hard.
Definining CASA 4.6 targets. Started discussion of plotter developments.
Discussion of the status of Solar fast scanning observations with Stephen White and Kazumasa Iwai.
21 Mon - 23 Wed: National holidays of Japan. You may not get active responses from NAOJ developers.
Wataru Kawasaki
made refactoring of SD baselining codes both for C++ and Python (tsdbaseline task code) sides since they have been quite lengthy.
