News / Meetings / Visitors
Edwardo Miranda: Demian is setting up a meeting for tomorrow.
Build, Release, Testing
Sorted Column: Push change into code.
Vi/VB2: Set's tile cache manually. (May move to release branch)
casacore: pull out for release then branch
Changes in the Sorted Column
Changes to allow writing to mms
CAS-7327: Will come in this week
Progress on continuum region identification, manual and automated region specification supported
Progress on AQUA report generation
Testing and bug fixing against CASA 4.5.
Confusion over ephemeris object direction (not spectral) reference frame
Fully flagged VBs flowing through to imaging, has now been prevented.
Fixed small things in task flagdata and in other tests to make them compatible with running on MMSs
Helped Pam to make test_plotms compatible with MMS and also with different DISPLAY settings
Helped to debug importasdm. It's leaving 2 ephemerides tables open in the cache. The same is happening with other tasks such as flagdata. This started to happen recently, I had fixed it sometime ago.
Tested George's modification to MSIter to make the SORTED_TABLE available only in memory. This was also making some MMS tests fail when run in combination with non-parallelised tasks. It seems to be fixed.
AQUA report generation work
Ephemeris coordinate system investigation
Improved test_plotms to work with MMS and on OSX 10.10
CAS-7777 - debugged Ed Fomalont's issue - filename too long with baseline iteration and large grid
CAS-4239 - fixed bug related to baseline length
CAS-7785 - fixed bug to prevent GUI from starting inadvertently when showgui=False
JIRA ticket review for easy/fixed issues
CAS-4092 - fixed task help xml files to standardize uvrange klambda examples
CAS-7607 - fixed Mac display spacing issues
Help from Ville to update libsakura on Mac to be able to compile
CAS-5137 - marked region persists when axes/iteration changes - cannot reproduce (fixed)
pinged users on a couple tickets
More debugging on shared axis/tarball issue
Fixed a bug in virtual model vis when the model image has the reference pixel off center
GridFT weight gridder now nearly gives the same density distribution as VisImagingWeight (accounting for known differences...like flag handling, mirror bug (see below))
there is something wrong since forever ..weight density calculation has a mirror reflection bug (i.e did not take into account that RA increment is negative ..where as it is taken into account in gridding...thus the point on the other side of the y axis density is used for Brigg's or uniform style weighting..which will be minor effect for most observations except for very sparse arrays or snapshots.

Viewer: CAS-7752: Blank dialog when loading fits images in casafeather (ready to test)
CARTA: Contour work
4 days in office
fix CAS-7329 LatticeHistograms segfault when setting a range outside of data range: Fixed. code merged to casacore
(CAS-4852) exportuvfits writes wrong field table information when multisource=False: Fixed
Requested purchase of new, faster Macbook from CIS since it takes several hours to build CASA on my current Macbook.
(CAS-7622) msmd.*forscan(s) methods should default to "any" obsid: Completed implementation, awaiting notification release branches have been created so I can commit this new feature to trunk/HEAD/whatever
(CAS-7327) SpectralCoordinate::frequencyToVelocity() returns nan's when rest frequency not set (rest freq = 0): Included a use case which illustrates the issue and returned assignment of the ticket to Dirk.
Participated in conversation regarding unit test configuration at multiple sites using different configurations and the confusion that presents to me as a developer.
Sought aid from Ville regarding updating libsakara on my Macbook. Thanks Ville!
(CAS-7589) ImageFitter segfaults with empty estimates file: Provided information on how to test to the test team.
(CAS-7621) Residual image not correct when fitting a single change of an image cube with a 2D fit: Provided information on how to test to the test team.
(CAS-7584) no random number seed in ia.addnoise() ?: Updated docs as user requested.
(CAS-7697) imstat(axes[0,1]) does not compute min/max correct if all data masked in a channel: Fixed and casacore code merged.
Discussion with Urvashi re: problem with image masks being left open by casacore code, referred her to Ger for more info since I wasn't involved in the design or implementation of the casacore mask-handling code.
(CAS-7770) msmd.sourcedirs returns 0,0 for ephemeris sources: A bit of a confusing discussion regarding the initial requirements I was given for this feature vs what the user may actually want, which seem to me that may contradict each other. In progress.
Dirk Petry *Worked on ephemeris object handling
(ICT-4143) "Implement proper handling of mosaics on ephemeris objects" is resolved.
(ICT-3873) "Fix ephemerides in ASDM" is resolved.
(CAS-7630) "The new ephemeris technique does not correct the UVW's upon importasdm" is ready-to-test
Discussed reference frame usage w.r.t. ephemerides in CASA with Lindsey et al.
Diagnosed and fixed casacore problem which made importasdm and cvel fail.
Worked on (CAS-7327) "SpectralCoordinate::frequencyToVelocity() returns nans" (have fix nearly ready)
Diagnosed (CAS-7789) "importasdm leaves ephemerides table open in cache", problem is in flagging code. Handed over to Sandra.
(CAS-7714) "importfitsidi: new optional parameters constobsid and scanreindexgap_s" is resolved
Continuing to integrate my work on visstat into the ms::statistics. [Considerable time spent in working on an MPI-IO bug for VLA.]
started investigation of dependency determination via cpp (i.e. xtc SuperC and jcpp)
refactored and tested running of selected tests on linux and osx (need to add tag option)
started testing with standard setup on RHEL5 (Villa moved osx tests to standard)
Various tclean bug fixes
Fixed image lock issue for image concat stage in parallel cube tclean
Fixed to tuneselectData to be used only for cube imaging
Fixed the remaining bug on multiple channel selections
Cube tclean issue - fixed the cube image made in wrong direction for the start parameter specified by velocity for the data with descending channel frequencies
Still investigating - shift in frequency grid in the cube image from what is specified in the input
Friday NAOJ Meeting
Kanako Sugimoto (I'll be out of office on Aug. 17th, 20th, and 21st)
Memo for Erik: discuss Jeff about collection of requests for CASA 4.6
