COVER INFORMATION Station: EFLSBERG (Code Ef ) Experiment: M87 high-resolution jet imaging Exp. Code: ek044 Schedule Version: 2.00 Processed by SCHED version: 11.50 Development version 11.5. Started Apr. 2 PI: Evgeniya Kravchenko Address: INAF Instituto di Radioastronomia via Piero Gobetti 101 40129 Bologna Italy Phone: +39 37 13530918 EMAIL: evgeniya.kravchenko@inaf.it Fax: +39 051 6399431 Phone during observation: +39 37 13530918 Observing mode: Notes: COVER LETTER: This is the schedule for single-epoch M87 observations at 1.3cm. It includes Jb2 Ef On60 Ur Tr Ys Sv Zc Bd Sr Mh Kt Ky Ku T6 Hh at a standard 1 Gbps continuum mode. Unfortunately, Mc and Nt are not available. Hh participation is highly desirable. Gaps between scans are adjusted to allow pointing for Effelsberg, which should be checked periodically (8 minute gaps every 2 hours). Fringe finder is 3C273 (two scans, for Asia and Europe). Kvazar has daily IVS sessions, and will quit during 1830-2130 UT.

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) 3C273 156.2 M87 155.9 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
