EVN: 4 Gbps, 16 IFs, 32 MHz filters, L+R, 2-bit sampling MER: 512Mbps/2IF/64MHz, UR: 2Gbps/8IF/32MHz, W1: 1 Gbps/4IF/32MHz Please DO NOT use the phase cal signal. COVER LETTER: This is the schedule for the 6cm NME and ftp fringe test on 1 November 2023 involving 11 EVN antennas + eMERLIN: Jb1, Wb, Ef, Mc, O8, T6, Ur, Tr, Ys, Hh, Ir, Cm, Da, Kn, Pi, De. Also Jb2 (J2) as a home-station back-up The NME uses a standard setup with a datarate of 4 Gbps, exc. MER(0.5G), UR(2G), Wb(1G). The NME lasts for 3 hours and consists of long scans on calibrators: J1751+0939 and J2031+1219. with ftp grabs every other scan at the following times (in UT): 12:10:00 (scan 2, 2 sec, J1751+0939) 12:40:00 (scan 4, 2 sec, J1751+0939) 13:10:00 (scan 6, 2 sec, J2031+1219) 13:40:00 (scan 8, 2 sec, J2031+1219) 14:10:00 (scan 10, 2 sec, J2031+1219) 14:40:00 (scan 12, 2 sec, J2031+1219) 14:59:00 (scan 14, 2 sec, J2031+1219) 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) J1751+0939 56.6 J2031+1219 94.8 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.
