The session uses a setup with 512 Mbps and consists of 3 ftp fringe tests, interspersed with a longer set of scans on 3C345 (source showing ~14 to 2 Jy correlated fluxes at 3.6cm). The three ftp fringe-test scans, start at: (1) 10:43:28 UT (scan 2, 2 sec) (2) 11:55:58 UT (scan 15, 2 sec) (3) 13:17:28 UT (scan 29, 2 sec) See you on Skype group chat and Good luck with the session!
