Survey - ICRF Frame - reduced by GSFC group - Aug 2001 The solar corona can cause unstable phases for sources too close to the Sun. 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) NGC3031 128.4 J0854+2006 166.8 J0921+6215 136.0 J0927+3902 153.6 J0958+6533 131.0 J1031+7441 122.3 J1048+7143 123.5 J1056+7011 123.9 J1101+6241 127.8 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.
