From gtaylor@cv3.cv.nrao.edu Wed Aug 16 03:56:55 2000 Date: Fri, 11 Aug 2000 23:36:17 -0600 (MDT) From: gtaylor To: Tim Cornwell , dshepher@zia.aoc.NRAO.EDU, julvesta@zia.aoc.NRAO.EDU, smyers@zia.aoc.NRAO.EDU, gmoellen@zia.aoc.NRAO.EDU Cc: gtaylor@zia.aoc.NRAO.EDU Subject: aips++ testing log for August 11th Testing AIPS++ Detailed Log Aug 11, 2000, session: note: TTT = trouble BBB = bug QQQ = question Waiting for further instructions from Athol about polarimetry calibration in aips++. So today I started out testing robustness of aips++ to failures. Killed imagr in mid stream. It gave the following sensible messages: "LocalExec::SetStatus: abnormal child termination for /home/sneffels3/aips++/stable/linux_egcs/bin/imager Server 'imager' has failed unexpectedly! You will need to create the relevant tool again. If that causes unexpected behavior, please restart AIPS++ Please submit a bug-report using bug() if you can reproduce the problem." Tried to just hit the 'Go' button again. This 'hung' the imager tool but I was able to delete the tool after a couple attempts. Made a new image but the Viewer crashed when I tried to look at my new image. Restarted aips++ and viewed my image ok. Enough of this. Decided to try out calibration of Q band data. Now using daily. aips++ hung my windows during Setjy for reasons unknown -- restarted. Restarted aips++ and got through setjy ok. In calibrater, fired up Tim's dgo.getantennas('qedt.ms') but all it does is make a tiny plot in the upper left corner of a pgplot window. Tim fixed this up and after restarting aips++ the plot looked sensible. Three points about it: 1) It show's antennas 1..28, but I happen to know that I didn't have 28 antennas (or even 27) since I'm at Q band. It should show only the antennas for which I have some raw data, or alternatively plot those invalid antennas in another color and not return them. If you select all then you get 1..28 inclusive. 2) Clicking on antennas is fine. It would be nice if one could also draw a box around a group of antennas. 3) It isn't real clear to me how to actually get this tool to feed the antennas you select into the calibrater tool. It should be integrated into the setdata command. Tried out some of the new editing/plotting features. This is a BIG IMPROVEMENT over what was there before. Now you can select discrepent points in a plot and flag them. Still needed: - Some way to select flagging on an antenna basis, even though you are looking at a single baseline to that antenna. - Some way to apply flagging commands to all spwid's and not just the displayed one. Same goes for polarizations and channels. - A plot of closure phases and amplitudes. - It would be nice if aips++ reported in the log what data it was flagging. --- end of testing.
