EVN: 1024 Mbps, L+R, 2-bit sampling, 8 BBC, 32 MHz filters MER: 512 Mbps, L+R, 2-bit sampling, 2 BBC, 64 MHz filters COVER LETTER: This is the schedule for the 18cm NME and ftp fringe test on June 8, 2023 involving 10 EVN antennas + eMERLIN: Jb2, Wb, Ef, Mc, Nt, O8, T6, Ur, Tr, Hh, Cm, Da, Kn, Pi, De. The NME uses a standard setup with a datarate of 1024 Mbps (512 Mbps for eMERLIN). The NME lasts for 3 hours and consists of long scans on calibrator J0956+2515 with ftp grabs every other scan at the following times (in UT): 12:10:00 (scan 2, 2 sec, J0956+2515) 12:40:00 (scan 4, 2 sec, J0956+2515) 13:10:00 (scan 6, 2 sec, J0956+2515) 13:40:00 (scan 8, 2 sec, J0956+2515) 14:10:00 (scan 10, 2 sec, J0956+2515) 14:40:00 (scan 12, 2 sec, J0956+2515) 14:57:00 (scan 14, 2 sec, J0956+2515) -- Junghwan Oh Mattermost: coms.evlbi.org Schedule for HART (Code Hh ) Page 2 Network Monitoring Experiment UP: D => Below limits; H => Below horizon mask; W => still slewing at end; blank => Up.

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) J0956+2515 65.9 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. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg
