Use a simple optimization mode to leave out scans for which the source ! is not above a specified elevation. opminel = 12 optmode = scans ! Alexander Kraus (email Mar 15 2004 in reply to evlbi@mpifr request) ! suggests 5 minute pointing scans every 2 hours for EB. ! Frank Ghigo suggests 8 minute gaps to point the GBT. He suggesting ! putting in the pointing source. ! For GBT Frank says do pointing every 30-45 minutes. ! I will put in pointing every 45 min or so for GBT and have EB use ! every other one. ! Use 3C273 for GBT and EB pointing when it is up. Otherwise use 1156+295 ! J1635+3808 was very compact and had 5 Jy in bw054e. ! But 1156+295 is also very compact, near 1 Jy, and much closer to M84. ! Put in a few scans of each for fringe finder, anplitude calibration ! source and possible polarization calibrator. ! I have to worry about tape passes for EB because it only has one tape drive. ! Will schedule in half pass blocks (11 minutes) with 3 between pointing. ! Is this really true for a one tape observation? I am explicitly not ! worrying about passes on the VLBA or GBT. ! -------------------------------------------------------------------------- ! Start VLBA with calibration/fringe find on 0420-014 and a look at M84. ! The M84 scan helps prevent SC from going on the wrong wrap. ! All antennas see 0420-014. The scans use the time needed by GBT and EB ! to point. Start GBT and EB with pointing on 1156+295. That should ! work for M84, although 3C273 will be better when it is up. ! Then get the first scans on 1156+295 and M84 with "all" antennas. The ! optmode will take out those antennas that are not up. record stations = SC, HN, NL, FD, LA, PT, KP, OV, BR, MK source = '0420-014' dwell = 5:00 / source = 'M84' dwell = 2:00 / norecord comment = ' ======== Pointing for GBT and EB ======== ' stations = GBT_VLBA, EB source = '1156+295' dwell = 10:00 / record stations = SC, HN, NL, FD, LA, PT, KP, OV, BR, MK, GBT_VLBA, EB source = '1156+295' dwell = 5:00 / source = 'M84' dwell = 6:00 / source = 'M84' dwell = 11:00 / source = '3C274' dwell = 2:00 / source = 'M84' dwell = 9:00 / source = 'M84' dwell = 2:00 / stations = SC, HN, NL, FD, LA, PT, KP, OV, BR, MK, EB source = 'M84' dwell = 9:00 / norecord comment = ' ============ Pointing for GBT ========== ' stations = GBT_VLBA source = '1156+295' dwell = 8:00 / group 15 rep 2 record stations = SC, HN, NL, FD, LA, PT, KP, OV, BR, MK, GBT_VLBA, EB source = 'M84' dwell = 11:00 / source = '3C274' dwell = 2:00 / source = 'M84' dwell = 9:00 / source = 'M84' dwell = 11:00 / stations = SC, HN, NL, FD, LA, PT, KP, OV, BR, MK source = '3C274' dwell = 2:00 / source = 'M84' dwell = 7:00 gap = 2:00 / !
