Stations testing their new DBBC backends are also included: YS_DBBC (Yd) and TM_DBBC (Td). The ftp test uses a USB-only/16MHz setup with 512 Mbps. The schedule consists of long integrations on QSO J0559+2353 (1 Jy at 5 GHz) and standard fringe finder DA193 (5 Jy at 5 GHz). There are two ftp fringe-test scans (1) 10:39:00 UT (scan 2, 2 sec, J0559+2353) (2) 11:15:00 UT (scan 6, 2 sec, DA193) Please make sure that the autoftp is set up correctly. See you on Skype group chat and Good luck with the session!

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) DA193 19.5 J0559+2353 11.5 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
