COVER INFORMATION Station: EFLSBERG (Code Ef ) Experiment: Network Monitoring Experiment Exp. Code: N23M1 Schedule Version: 2.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: Suma Murthy Address: JIVE Oude Hoogeveensedijk 4 7991 PD Dwingeloo The Netherlands Phone: +31-521-596507 EMAIL: murthy@jive.eu Fax: Phone during observation: +31-521-596507 Observing mode: Notes: 5cm NME and ftp fringe test for Session 2 2023 (256 Mbps, L+R, 2-bit sampling, 4 MHz filters) 3 modes: for excited-OH (6030/35) and methanol (6667), and a centered methanol maser Please DO NOT use the phase cal signal. COVER LETTER: This is the schedule for the 5cm NME and ftp fringe-test on 2021, November 03 involving antennas: Jb2, Wb, Ef, Mc, Nt, On85, Tr, Ys, Ib. We shall test two setups: for the OH line and CH3OH line both with 256 Mbps. The schedule consists of long integrations on J0854+2006 for the fringe test with J0905+2052 as phase reference calibrator. In the end we will observe a Maser J0608+2138 with J0603+2159 as the phase-reference source. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 14:08:00 (scan 1, 2 sec, J0854+2006) Setup 1 14:30:00 (scan 3, 2 sec, J0854+2006) Setup 1 15:00:00 (scan 5, 2 sec, J0854+2006) Setup 1 Change to Setup 2 at Scan 6 (15:04:00) 15:30:00 (scan 9, 2 sec, J0854+2006) Setup 2 16:00:00 (scan 13, 2 sec, J0854+2006) Setup 2 16:30:00 (scan 17, 2 sec, J0854+2006) Setup 2 May you be the master of masers!

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) J0905+2052 65.0 J0608+2138 24.4 J0603+2159 23.2 J0854+2006 62.8 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
