The NME uses a standard setup with 1024 Mbps (512 Mbps for eMERLIN). The schedule has two segments: 12:00-14:15 long scans on J0237+2848 with ftp grabs every other scan (18cm setup); 14:20-15:00 a long scan on J0730+4049 with an ftp grab then alternating short scans on J0730+4049 and J0727+4052 with an ftp grab in scans 17 and 23 (21cm setup). The following ftp-fringe tests are scheduled throughout the experiment (UT times): 12:10:00 (scan 2, 2 sec, J0237+2848, 18cm setup) 12:40:00 (scan 4, 2 sec, J0237+2848, 18cm setup) 13:10:00 (scan 6, 2 sec, J0237+2848, 18cm setup) 13:40:00 (scan 8, 2 sec, J0237+2848, 18cm setup) 14:10:00 (scan 10, 2 sec, J0237+2848, 18cm setup) 14:25:00 (scan 12, 2 sec, J0730+4049, 21cm setup) 14:41:00 (scan 17, 2 sec, J0730+4049, 21cm setup) 14:56:00 (scan 23, 2 sec, J0730+4049, 21cm setup) Thank you for taking part in this NME.

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) J0237+2848 71.0 J0730+4049 129.6 J0727+4052 129.1 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.
