The session uses a setup with 1024 Mbps and consists of three ftp fringe tests, interspersed with a longer set of scans on 0716+714 (~2 Jy source at 1mm). The three ftp fringe-test scans, start at: (1) 15:13:28 UT (scan 2, 2 sec) (2) 16:26:58 UT (scan 10, 2 sec) (3) 17:45:28 UT (scan 18, 2 sec) See you on Skype group chat and Good luck with the session!
