The NME uses a setup with 1 Gbps and consists of integrations on strong calibrators like 4C39.25 (~8.3 Jy at 15 GHz from MOJAVE) and J1310+3220 (~2.5 Jy at 22GHz from EVLA POLCAL Database) as well as phase-referencing cycles with continuum calibrators (J0923+3849) as targets. There are three ftp fringe-test scans (1) 12:09:00 UT (scan 2, 2 sec, 4C39.25) (2) 12:55:00 UT (scan 25, 2 sec, 4C39.25) (3) 13:49:00 UT (scan 49, 2 sec, J0923+3849) See you on Skype group chat and Good luck with the session!
