COVER INFORMATION Station: SVETLOE (Code Sv ) Experiment: A second active nucleus in Cygnus A? Exp. Code: EB060A Schedule Version: 1.00 Processed by SCHED version: 11.40 Release 11.4. March 14, 2015 PI: Uwe Bach Address: Max-Planck-Institut fuer Radioastronomie Auf dem Huegel 69 53121 Bonn Germany Phone: 0049-2257-301-168 EMAIL: ubach@mpifr-bonn.mpg.de Fax: 0049-2257-301-106 Phone during observation: 0049-2257-301-155 Observing mode: Notes: Use 2013+370 as fring tracer and BL Lac as 2nd calibrators COVER LETTER: This is the schedule for epoch A of EB060 at 1.3cm. It involves 15 antennas Jb2, Ef, Mc, Nt, On60, Tr, Ys, Sv, Zc, Bd, Hh, Mh, Kt, Ky, and Ku and runs at a standard 1 Gbps continuum mode. Gaps between scans are adjusted to allow time for Tsys measurements on source and some pointing time every 1.5 hours, because the observation happen during sunrise at Effelsberg. Fringe finders are 2013+370 and BL Lac. Schedule for SVETLOE (Code Sv ) Page 2 A second active nucleus in Cygnus A?

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) CYG-A 64.1 2013+370 59.5 BLLAC 49.8 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.
