The second is 1 hour of single band dual pol X band. It is expected stations will require ~ 1 hour to change receivers between the tests. The schedule consists of long integrations on strong calibrators: Ftp-fringe tests are scheduled ~ every twenty minutes throughout the experiment: 12:10:00 scan 2 J1848+3219 12:30:00 scan 4 J1848+3219 12:50:00 scan 6 J1848+3219 Gap for setup change 13:30:00 scan 8 J1848+3219 13:50:00 scan 10 J1848+3219 14:10:00 scan 12 J1848+3219 14:30:00 scan 14 J1848+3219 14:50:00 scan 16 J1848+3219 Clear skies!

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) J1848+3219 85.3 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
