Code: N22L1 Schedule Version: 1.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: Gabor Orosz Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31 686337748 EMAIL: orosz@jive.eu Fax: Phone during observation: +31 521 596 508 Observing mode: Notes: L-band (18/21cm) NME and ftp fringe test for Session 1, 2022. 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 Including 21cm mode in last half hour for FAST COVER LETTER: This is the schedule for the 18cm NME and ftp fringe-test on February 24, 2022 involving 14 EVN antennas + eMERLIN + FAST: Jb1, Wb, Ef, Mc, Nt, O8, T6, Ur, Tr, Hh, Sv, Zc, Bd, Ir, Cm, Da, Kn, Pi, De, Fa. 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.
