The distance from the Sun to each source in this schedule is: Source Sun distance (deg) 0716+714 71.0 3C273B 146.3 3C279 155.9 1633+382 119.4 3C345 117.1 1749+096 123.9 1921-293 110.5 2145+067 68.8 P-TXCAM 50.8 P-GXMON 65.1 P-RLMI 97.1 P-SCRB 132.3 P-UHER 135.6 P-AHSCO 138.8 P-VXSGR 127.4 DR21 78.1 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.
