The NME uses a standard 512 Mbps setup. The schedule consists of long integrations on strong calibrators (J0126+2559, J1051+2119) for ftp-fringe tests. (J1026+2559 ~1.4Jy/beam, J1051+2119 ~1.3Jy/beam) Four ftp-fringe tests are scheduled throughout the experiment: 12:09:00 (scan 2, 2 sec, J0126+2559) 13:15:00 (scan 8, 2 sec, J0126+2559) 13:43:00 (scan 11, 2 sec, J1051+2119) 14:49:00 (scan 17, 2 sec, J1051+2119) All antennas will participate in at least two FTP fringe tests. Please make sure that the autoftp is set up correctly. Thanks! Good luck with the session and see you on Skype!

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) J0126+2559 45.8 J1051+2119 82.8 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg
