Stations testing their new DBBC backends are also included: MC_DBBC (Md), TR_DBBC (Td), and YS_DBBC (Yd). The NME uses a setup with 1 Gbps and consists of integrations on the VLBI fringe finder DA193 (~1.8Jy at 22 GHz) as well as phase-referencing cycles between continuum calibrators (1st phase-reference cycle: J2040+4527 -- J2039+4159; 2nd phase-reference cycle: DA193 -- J0605+4030). There are three ftp fringe-test scans (1) 14:09:00 UT (scan 2, 2 sec, DA193) (2) 15:31:00 UT (scan 38, 2 sec, DA193) (3) 16:29:00 UT (scan 69, 2 sec, DA193) See you on Skype group chat and Good luck with the session!
