The session uses a setup with 1024 Mbps and consists of three ftp fringe tests, interspersed with a longer set of scans on 0836+710 (~2 Jy source at 2cm, although not pointlike). The three ftp fringe-test scans, start at: (1) 12:07:28 UT (scan 2, 2 sec) (2) 13:29:58 UT (scan 12, 2 sec) (3) 14:53:58 UT (scan 23, 2 sec) See you on Skype group chat and Good luck with the session!
