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 25 October 2024 involving 11 EVN antennas + eMERLIN: Jb2, Wb, Ef, O8, T6, Ur, Tr, Ys, Hh, Ir, Sr, Cm, Da, Kn, Pi, De. The NME uses a standard setup with a datarate of 4 Gbps, with eMERLIN at 0.5 Gbps, Ur at 2 Gbps, and Wb at 1 Gbps. 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!
