The ftp test uses a standard 512 Mbps setup. The schedule consists of long integrations on VLBI calibrators J1329+3154 (~1 Jy at 8.6 GHz from the VLBA calibrator Survey) and J1613+3412 (~2 Jy at 8.6 GHz from the VLBA calibrator Survey). There are two ftp fringe-test scans (1) 09:06:00 UT (scan 2, 2 sec, J1329+3154) (2) 09:50:00 UT (scan 6, 2 sec, J1613+3412) Please make sure that the autoftp is set up correctly. See you on Skype group chat and Good luck with the session!

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) J1329+3154 42.3 J1613+3412 57.7 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
