From block schedule. allocated ! ! Eb, Wb, Jb1, Mc, Nt, Tr, + VLBA(-MK) ! This schedule file is for EVN antennas 1024Mbps ! ! day 80, March 21th Sunday, EU 1200 - 2000, 1024Mbps ! US 1200 - 2000, 512Mbps 5GHz global network observation of 3C48. Since the different data recording rate of the EVN and VLBA, two different schedule files are made for EVN and VLBA respectively. The correlation position is 120 mas north of the active nucleus, at a component B2, RA 01 37 41.29949, DEC +33 09 35.1338. This setup enables to less degradation of flux density in both VLBI core region and shock-induced blobs in the north jet. One correlation pass is sufficient. A dual polarisation mode is used and cross-correlation products requested. The sources 3C138 is used as EVPA calibrator, will be observed 2 scans DA193 is used as D-term calibrator, will be observed 6 scans Schedule for WSTRBORK (Code Wb ) Page 2 3C48 6cm UP: D => Below limits; H => Below horizon mask. blank => Up.

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) 3C48 39.7 3C138 79.9 DA193 88.4 3C345 105.0 3C454.3 23.2 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
