Still debugging joint A+W problem.
Discussions many, including with Preshanth about full-Mueller imaging work and with Li on Asp-Clean kind of deconvolution
Investigations on differences between measured and modeled cross-polar beam patterns
CAS-5833: After waiting for Steve's input, got George's explanation on what this ticket wants. MANY thanks George. The first part, to support SYSPOWER caltables in flagdata is already implemented. Did they ever try it before putting up this request??? Of course, Steve blamed the documentation, which already contained information on all possible supported datacolumns!!! I updated the documentation to become even longer and more redundant. The second part of this ticket, to create flag commands from selected rows of the SYSPOWER MS sub-table will be more complicated. Some issues are:
There is no support for SYSPOWER table in casacore/ms/MeasurementSets. Who should include this?
There is no iterator for sub-tables in CASA.
I asked Ger for information on some table selector in casacore that would interpret MSSelection syntax. He pointed me to mscal, which I will look at this week.
Tested new package releases in OSX.
Implemented QA estimators for several pipeline tasks
Follow up on pipeline acceptance blocker tickets
Development process discussions
Justo González Villalba
Writing user and advance developer guide for new MPI-based parallelization framework
Made a presentation in ESO about new MPI-based parallelization framework
Preparing extra content for the coming CASA Technical Telecon presentation
Prepared a benchmark script for a parallel version of the CASAvsAIPS regression.
Continuing work on Carta UI Design
Attending imaging workshop.
Need to schedule Lindsey's pipeline talk (June 12 or 26th?)
Baseline dependent averaging: how to specify uvw movement averaging limit?
Actually did a small amount of investigation into BP-Dip issue.
Susan Loveland: Fixed viewer bugs (4.2.1 & trunk) and worked on CARTA UI prototype.
David Mehringer: completed reimplementation of unmaintainable method ImageAnalysis::getFreqProfile() to PixelValueManipulator::getProfile(). Also completed CLI to this method, ia.getprofile().
Investigated status of sigma/weights in split & mstransform. Mostly this looks like we just need to sort out nchan (at least in mstransform). An email to Justo is forthcoming.
CAS-4071: Established beyond any reasonable doubt that the 'bpdip' is a statistical artifact. In particular, ALMA's higher frequency bands tend to be subject to lower SNR bandpass calibrators and so per-integration solutions on subsets of channels are especially prone to this effect (most reports are at band 7 and 9)
NRAO Synthesis Summer School prep: a) my Calibration lecture, which is Wed morning; b) data reduction tutorial sanity checks on NMTech machines, etc. (seems ok)
Minor additions to 'tcean' task interface, logger message cleanup, started adding clark/msclean minor cycle algorithms.
Worked on (long overdue) paper about characterizing VLA imaging limits with various algorithms.
Initial discussion with Henrik Junklewitz (visitor from Garching) about adding two RM-synthesis algorithms into CASA (via me). His code is currently in use at LOFAR.
Darrell Schiebel AAT/PPI review, tweaks to casacore include in RPM, debugging threading in DBus VO Service, sick, and vacation
4.2 Post mortem discussions
Documentation repository implementation (& breaking Jenkins in the process)
JIRA Subversion plugin
Takahiro Tsutsumi: Mostly worked on refactoring setjy for unnessary per-spw processing (created CAS-6530 to track this)
Friday NAOJ Meeting
Kanako Sugimoto (will be out of office: May 19-21)
discussed about CASA 4.3 additional targets with Bunyo
sent a list of SD developments (commit revisions) to merge to release-4_2_2 branch
some comments on single dish weight discussion ( CAS-6181)
