The distance from the Sun to each source in this schedule is: Source Sun distance (deg) 3C454.3 47.8 J0217+0144 11.6 J0555+3948 55.6 J2334+0736 39.0 R_AQR 46.4 O_CETI 16.3 U_ORI 53.9 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
