COVER LETTER: Dear EVN friends, This is the schedule for the 1.3cm NME on Oct. 17 2013, involving 17 stations: Eb Jb2 On20 Mc Nt Tr Ys Mh Sv Zc Bd Ur Sh Hh Ky Ku Kt The NME uses a setup with 1 Gbps and consists of integrations on strong calibrators (OJ287, 4C39.25, 0836+710, with ~5, ~8, and ~2.3 Jy at 15GHz as reported by the MOJAVE Team) as well as phase-referencing cycles involving 4C39.25 and a continuum calibrator (J0916+3854) as targets. There are three ftp fringe-test scans starting at: (1) 03:35:40 UT (scan 2, 2 sec, OJ287) (2) 03:59:40 UT (scan 6, 2 sec, 4C39.25) (3) 05:52:50 UT (scan 65, 2 sec, 4C39.25) See you on Skype group chat and Good luck with the session!
