Any Other Business

  • Additional viewer testing: Juergen, Nuria, plus?
  • 4.3 planning is under way. We will begin assigning 4.3 testing tasks to user testers in the next few weeks.
  • Juergen invites user tester comments regarding input and improvements to the cookbook.

  • Jeff identified a shortlist of key items remaining for the 4.2 release during the last meeting. Restating these briefly here:
    • CAS-3116: Comprehensive computation of spectral index from image(s). George's documentation.
    • CAS-5213: Feather GUI Blocker.
    • CAS-5127: ia toolkit documentation.
    • CAS-5206: Test regridding of GBT Data on 4.2 as well. Note: no GBT-related items regarded as blockers for the 4.2 release.
    • CAS-5044: Flagging by weight.
    • CAS-5719 (Oct): view pv-diagram crashes viewer. (Should already be fixed, just needs to be retested).

PART 1: Items To Be Covered During Meetings

Ready to Close Items

    • CAS-5172 (Jun): Add capability for fftshift to regridding portion of MSTransform. To be tested as part of CAS-4754. Juergen's done some testing of this, but Adam could help if necessary. Some follow-up work done by the developers (r26435). ARTT in casapy-test r26662+. Ticket pinged for an update. Tester: Juergen. Juergen thought it looked reasonable now. Following the previous meeting, he was going to talk to Justo before confirming this as resolvable.

Items Overdue for Status Updates (i.e. the "Nag List")

  • CAS-5127 (May): Document ia toolkit methods. Status In Progress. Mark is working on this. Will probably cover at least Juergen's prioritized list of 26 items for the release. Mark will also add dates to his future documentation updates. Prioritized by Mark. Ongoing.
  • CAS-3116 (Jun): Comprehensive computation of spectral index from image(s). Laura Perez is testing this for the VLA. ALMA will hold off on testing this for now, pending the VLA testing. Latest fix was (r26751). Currently Input Required in casapy-test (r6919+). Laura had done some testing. Thought this one was close to being closed, but additional issues encountered. Note: will need a new tester (Laura on travel for two weeks).
  • CAS-5335 (Jul): CASA Region Text File pixel sizes not handled properly. Blocker. Currently listed as "Open". Parked with Mark. At least some of the blocker aspects have hopefully now been addressed by the developer - see below: ARTT subtasks testing needed to establish if this is no longer a blocker.
    • CAS-5572 (Sep): Test fix for circles and ellipses when image has non-square pixels. Subtask of CAS-5335. ARTT in casapy-test (r26662+). Tester: Amy.
    • CAS-5589 (Sep): Test cos(dec) fix to ensure region sizes are invariant upon shifts in dec. Subtask of CAS-5335. ARTT in casapy-test (r26662+). Tester: Amy.
  • CAS-5213 (Jul): feathering GUI (casafeather) upgrade. Upgraded to Blocker. Brian Mason and Juergen did some testing of this, and are working on documentation. Issues had been reported to the developer recently, but he cannot reproduce them. Beam volumes work committed as r27170. RTT, pending a new testable package (most recent commit was r27181).
  • CAS-5248 (Aug/Sep): propagate gridding and beam changes to simanalyze. ARTT in casapy-test r26662+ (but previously partly tested in private build). Tester: Jen. Lots of back and forth. Testing ongoing. Brian expects the remaining issues to be resolved with in the next couple of weeks. Brian has provided a document.
  • CAS-4754 - MSTransform subtasks: Lots of testing done. time averaging stuff being tested now. MSTransform will be marked as "experimental" in the 4.2 release.
    • CAS-5013 (Jul): "cvel handling of different sensitivity spw". ARTT in July stable+. Subtask of CAS-4754. Ticket passed to Anita in Europe as part of the general MSTransform testing effort there. Testing is ongoing: it mostly seems to work, but a few questions remain (covered in the parent ticket for combined MSTransform testing (CAS-5581). This older ticket may be close to resolving, though?
    • CAS-5581 - Test of MSTransform capabilities in combination. ARTT. Most recent commit was r26622 - now in latest casapy-test. Currently being tested by Anita Richards. Time average in new split now available (r26919). Remaining issue(s) being investigated. Ongoing.
    • CAS-4849 (Oct): Enhanced Split Capabilities: Time Averaging. Currently ARTT - in current casapy-test (26919+). Some caveats in ticket. Tester Anita.
    • CAS-4850 (Oct): Enhanced Split Capabilities: Baseline Dependent Time Averaging. Currently ARTT - in current casapy-test (26919+). Some caveats in ticket. Tester Anita.

Single Dish (to be skipped during the meeting)
  • CAS-4772 (Mar): Implement Tsys calibration task. Currently ARTT in casapy-test (r26662+). Tester: Shinya. Ticket pinged for an update Oct. 24th.
  • CAS-5496 (Sep): sdflag2: enable data selection by time range. Currently ARTT in casapy-test. Tester: Daniel Espada

Tested by Mark and it now at least runs. However, ds9 pre-rotated images remain problematic (this would be for some future release, though - not now). Some bugfixes put in. To be tested again once they are available.
  • CAS-5532 (Oct): Exportfits should respond to the conversion layer in CASA Images. Open again (had been resolved as done). Lingering bug reported by Adam. Example info requested by developer, and recently provided by tester. Tester: Adam
  • CAS-5695 (Oct): msmd "forintent" methods should allow wildcards in intent names. RTT again, pending new casapy-test . Latest commit was r26969. Todd to test.

  • CAS-5123 (May): Support for On the Fly Mosaics. Currently ARTT. JAO (ALMA) and Socorro (VLA) to test. Awaiting suitable data from ALMA. Steve has done some work on this for VLA. Still waiting on data; unlikely to be fully tested before release. Ticket's with Steve now. Have recently been in the process of doing tests on the VLA with some data scanning across bright sources. Kunal to test this when ready to invoke the imaging. Question: does this one get bumped to 4.3?
  • CAS-5706 (Oct): msmd.spwsforfield returns the wrong answer (Blank) if the specified field name has two IDs. Todd to test this. Currently RTT, pending a newer test package. Commit was r26931.
  • CAS-5431 slicing in frequency selection throws exception. Set to Input Required and passed back to dev. Tester: Kumar.
  • CAS-5502 (Aug): Velocity regridding in viewer sometimes not available. Currently RTT again. Tester: Adam. New fix committed as r27341 (trunk) and r27323 (release). Blocker.

Single Dish
  • CAS-4771 (Mar): Implement sky calibration task. Seemed to work, pending final check of one set of suspicious input data. However, new bug fix put in. Currently RTT again. Tester: Bunyo (was Shinya).
  • CAS-5138 (Aug): Make default image area of sdimaging cover the pointings in MS. Shinya has been testing this. Set back to RTT again for retesting (commit: r27041).

Other Blockers

  • CAS-5789 SD tasks are not working on mixed mode data (TDM and FDM in same dataset). Blocker. Crystal says that with the appropriate documentation updates, this one may now be resolved.
  • CAS-4946 Crash on Mac OS X when virtual model requested. Blocker. Recently re-checked by Nathan, and it now sounds as if this still affects Mac OS X 10.6, but not 10.7 or 10.8. Debugging code pops up for all, though.
  • Also, Mac OS X 10.7 Qt stuff: CAS-4310, 4602.

4.2 Release "As Is" Items

  • CAS-2252 (May): calculate the rotation measure. VLA item. Currently ARTT Will be released "as is". Testing done by Steve, but still inconclusive.

Items Descoped from CASA 4.2

  • CAS-5111 (May): Implement autoboxing capability. Currently RTT. This one had previously been ARTT, and Crystal had looked at this and provided a problem case. A fix had been put in and tested by Steve. He has provided feedback: seems to sort of work, but still fiddly right now. Ticket is currently set to "Ready To Test" and assigned to Tony, so that he can try it with both the M100 and Orion datasets. Lots of comments provided by John Lightfoot. A meeting has taken place on this, and it is an ongoing development topic. Ongoing development will be target of 4.3 Cycle.
  • CAS-5125 (Jul): Make frequency an axis display option (in the viewer). Previously ARTT, currently Open. Tester: Adam. Tested. Needs more work and so ticket back to dev. Pinged Oct. 22nd: possibly deprecated? Will probably not now make it into the 4.2 release.
  • CAS-5379 - Subtle inconsistencies with other programs in Galactic Coordinates (Adam and Harvey). In a nutshell, shifts of ~0.2" are seen when taking data into other packages (e.g. DS9, IDL which both seem to agree with each other). It is unclear yet if this is an incorrect implementation in one or more packages, or possibly just a precision error. This is a subtle issue, and has been pushed back to 4.3.
  • CAS-3517 (Aug): Improve remapping interface (Cal libraries). Currently ARTT in casapy-test r26325+. Tester: Steve. Some testing done, recommendations made. Discussion ongoing. Further callibrary work to be pushed out to 4.3 in Jira.
