It uses 1 THIN tape per station. The Fringe Tape will be correlated at JIVE. To enable quick feedback, please send the tape as soon as possible (with express mail) to the JIVE correlator. Thank you for your efforts. Good luck with the session. Schedule for SHANGHAI (Code Sh ) Page 2 Fringe Tape K band - Session 1 2004 UP: D => Below limits; H => Below horizon mask. blank => Up.

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) 0133+476 87.5 2200+420 59.9 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
