COVER INFORMATION Station: HART (Code Hh ) Experiment: A second active nucleus in Cygnus A? Exp. Code: EB060C Schedule Version: 2.00 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 B of EB060 at 6cm. It involves 15 antennas Jb2, Ef, Wb, Mc, Nt, On85, T6, Ur, Tr, Ys, Sv, Zc, Bd, Hh, and Ir and runs at a standard 1 Gbps continuum mode. There are two gaps to allow some pointings at Effelsberg. Fringe finders are 2013+370 and BL Lac. Schedule for HART (Code Hh ) Page 2 A second active nucleus in Cygnus A? UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up. Early: Seconds between end of slew and start. Dwell: On source seconds. Disk: GBytes recorded to this point. TPStart: Recording start time. Frequencies are LO sum (band edge).
