EVN: 2048 Mbps, 8 IFs, 32 MHz filters, L+R, 2-bit sampling Wb: 1 Gbps, 4 IFs, 32MHz Please DO NOT use the phase cal signal. COVER LETTER: This is the schedule for the 3.6cm NME and ftp fringe-test on 3 March 2025 involving the following 11 antennas: Wb1, Ef, Mc, Nt, On60, T6, Ur, Tr, Ys, Hh, Km, Wz. The NME uses a standard 2 Gbps setup (16 BBCs, 32 MHz, dual pol), exc. Wb1 (1 Gbps). The NME lasts for 3 hours (12:00-15:00 UT) with long scans on the calibrators: J0237+2848, J0319+4130 (3C84) and J0530+1331 J0528+1317 is used as phase-referenced source, for testing purposes, in the last hour. with ftp grabs every other scan at the following times (in UT): 12:10:00 (scan 2, 2 sec, J0237+2848) 12:40:00 (scan 4, 2 sec, J0237+2848) 13:10:00 (scan 6, 2 sec, J0237+2848) 13:40:00 (scan 8, 2 sec, J0319+4130) 14:10:00 (scan 10, 2 sec, J0319+4130) 14:35:00 (scan 16, 2 sec, J0530+1331) 14:58:00 (scan 22, 2 sec, J0530+1331) -- Benito Marcote 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.
