NRAO AIPS++ Users Group Meeting - DRAFT MINUTES Date: 2005-05-25 (Wednesday) Time: 1300 MDT Video Hub: SOC-conf (CV should call in to Socorro) Rooms: SOC317/CV311 Send additions and corrections to smyers 1. NAUG News o general news (Steve) 2. AIPS++/ISD Status Report o stable status (Kumar) As of Tuesday May 24 there is a stable SS11 that should be used for the EVLA testing. This is accessed as version "stable". o defect status (Kumar) There was no defect day in May, perhaps next in late June (maybe an afternoon of the developers workshop could be devoted to defect bashing?). o development targets (Kumar) There is an aips++ developers workshop scheduled for June 6-11. This will be held at the AOC. o Mac support There were requests for Mac support for the EVLA testing, particularly since a number of the testers had G5s or powerbooks with enough memory. It appears that there are some issues with compiling glish. Might be some problems for the latest OS10 version (Tiger?). Wes should be able to help/clarify these issues. This porting should be greatly aided by the move to python ... 3. ALMA o ALMA Test 3 (A2005.1/TST2.0) testing results (Kumar, Steve) All external testers have submitted their reports. See http://projectoffice.aips2.nrao.edu/almatst2.0/ALMA_TST2.0.html (near the bottom) for links to the individual testers results. Eventually a report will be compiled as in previous tests. Crystal had some interesting "additional comments" http://aips2.nrao.edu/projectoffice/almatst2.0/Comparison/brogan/comments (this is exactly the sort of thing we like from testers!). It is my (STM) assessment that there needs to be some significant algorithm development work in the area of multi-scale deconvolution and mosaicing (w/single dish) for ALMA. Job for the Science IPT and ImCal group... 4. EVLA o EVLA Test 1 (E2005.1) testing status (Joe, Steve, Sanjay) See below. 5. Main Event - Presentations and Discussion Items o Testing status for EVLA 2005.1 tests ************************************************************************** - See the testing page for details: http://projectoffice.aips2.nrao.edu/evlatst2.0/EVLA_TST2.0.html In particular see the Goals & Scope: http://aips2.nrao.edu/projectoffice/evlatst2.0/test.scope.txt Also the Hints & Caveats: http://aips2.nrao.edu/projectoffice/evlatst2.0/EVLATST_hints.txt Testing data can be found from the web page, although these are links to a local disk area (/home/rohir2/jmcmulli/EVLATST1/Data/) so CV testers will have have to scp these over (and they are big, so do this overnight or over weekend). Discussion: - The stable (SS11) is ready for testing (see above). - The target for test completion is Monday June 27. - Testers will want to use computers with as much RAM as possible. For the 1046 dataset, will want 2GB which should allow 7200x7200 images. In 1GB can do 3000x3000. Note that the imager-a, imager-b, imager-c machines are available and have 2GB. Be sure you're the only one running! (I think Walter has already nabbed imager-c.) - The 1046 and AXAF datasets were pre-tested by the aips++ groups. For 1046, images were obtained that were comparable (in flux and noise level) to those obtained by Frazer using AIPS and by Tim and Frazer using aips++ (comparison images available). Ed will produce a comparison image (in AIPS) for the AXAF field during his testing. - The main testing for 1046 is to use the dataset with "flanking field" sources already subtracted (the Shk116/1046P59.ABCD34.FITS dataset). Once that has been run through, if there is time we recommend testers try out doing the outlier sources in aips++ by making low-res images to find sources and then putting extra fields around them. It was commented that using NVSS would be difficult due to the deepness of this data and the overwhelming number of NVSS targets in the area, but might be worth trying. - The AXAF data (which is C-config) can probably get by with a single big image, though it is worth checking this out by making a tapered extra wide image. - The pre-testing used basic comparisons like spot-checking fluxes of sources and looking at noise levels in blank areas (as well as checking visually for quality and artifacts). It would be good to come up with some good metrics for automated comparisons, particularly when we include these datasets in regression tests. Some possibilities like differencing images were discussed (beware of different restoring beams etc.). - Walter has started testing. Ed is planning to come to the AOC in June for testing, probably the week of June 6-10 (overlapping with the Developers Workshop). Frazer may be able to get to it late in June (hopefully before the closing date of June 27). Steve will start next week. Unsure about Bryan and Gustaaf. ************************************************************************** o Tasking interface status and demonstration (deferred) Hopefully at the next NAUG that Joe is here for... 6.
