The distance from the Sun to each source in this schedule is: Source Sun distance (deg) NGC3998 130.5 J1058+8114 107.2 J1128+5925 128.2 NGC3894 127.4 1156+295 152.0 3C286 134.4 J1347+1217 133.7 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
