TTT> after trying to launch documentation with 'web()' from Glish my maching hung and had to be rebooted. Some files were corrupted on disk so I had to get help from George Martin. Lots of time lost. Restarted aips++ ok. 'web()' worked ok. Resolution: None, can't get the problem to repeat. TTT> can't get the GUI for setjy to come up. Dragged Athol into my office where he tried to rebuild daily for me. It appears to have broken the previous day. This also prompted a message from Athol about what version we should be testing. Resolution: If it doesn't work in daily, try weekly. Successfully ran setjy in daily. BBB> Next comes the calibrater tool. Unfortuntately there is still no easy way to set a UV restriction. I asked for this back in April. Athol says that they are actively working on implementing this. It is critical to the VLA calibration path so I hope so. In the mean time, in msselect put for 3C286, B config, 6cm: (field_id==2) && (UVW[1]^2 + UVW[2]^2 + UVW[3]^2 < (25000*0.06)^2) No easy way to restrict the number of antennas so I let that slide for now. BUG 000728 reported: When calibrating VLA data one almost always need to put in a u,v range and antenna restriction for the primary flux calibrator (e.g. 3C286). This is possible but very cumbersome right now, for example: (field_id==2) && (UVW[1]^2 + UVW[2]^2 + UVW[3]^2 < (25000*0.06)^2) And would be even worse if I had bothered to set the antennas. There needs to be a simple interface to put in a u,v range and to select some subset of the antennas (it would nice if they were layed out and one could graphically select them, but just putting in antenna numbers would be ok). Ran through the calibration and derived the following: Set the flux density scale using reference calibrators Flux density for 1751+096 (spw=1) is: 2.040 +/- 0.002 Jy Flux density for 1751+096 (spw=2) is: 2.034 +/- 0.002 Jy Flux density for 1743-038 (spw=1) is: 4.469 +/- 0.003 Jy Flux density for 1743-038 (spw=2) is: 4.451 +/- 0.005 Jy Flux density for 1337-129 (spw=1) is: 5.477 +/- 0.004 Jy Flux density for 1337-129 (spw=2) is: 5.406 +/- 0.006 Jy Flux density for 1310+323 (spw=1) is: 1.856 +/- 0.001 Jy Flux density for 1310+323 (spw=2) is: 1.849 +/- 0.002 Jy Flux density for 0854+201 (spw=1) is: 2.385 +/- 0.002 Jy Flux density for 0854+201 (spw=2) is: 2.376 +/- 0.003 Jy Flux density for 1534-354 (spw=1) is: 0.566 +/- 0.000 Jy Flux density for 1534-354 (spw=2) is: 0.562 +/- 0.001 Jy Flux density for 1252-336 (spw=1) is: 0.434 +/- 0.000 Jy Flux density for 1252-336 (spw=2) is: 0.432 +/- 0.001 Jy Flux density for 1337-129 (spw=1) is: 5.477 +/- 0.004 Jy Flux density for 1337-129 (spw=2) is: 5.406 +/- 0.006 Jy Flux density for 0713+438 (spw=1) is: 1.538 +/- 0.001 Jy Flux density for 0713+438 (spw=2) is: 1.545 +/- 0.002 Jy Flux density for 0927+390 (spw=1) is: 10.609 +/- 0.007 Jy Flux density for 0927+390 (spw=2) is: 10.499 +/- 0.012 Jy Visibility plots look reasonable except for a lot of scatter on 3C286, bad data? --- end of testing.
