Started Apr. 2 PI: Olga Bayandina Address: JIVE Oude Hoogeveensedijk 4 7991PD Dwingeloo The Netherlands Phone: +31-521-596508 EMAIL: bayandina@jive.eu Fax: Phone during observation: +31-521-596508 Observing mode: Notes: K-Band NME and ftp fringe test for session 3/2019 (1024 Mbps, L+R, 2-bit sampling, 16 MHz filters) Please send the disk pack by express to JIVE Please DO NOT use the phase cal signal. COVER LETTER: This is the schedule for the K-band NME and ftp fringe-test on 17 October 2019 involving antennas: Jb2, Ef, Mc, On60, T6, Ur, Tr, Ys, Hh, Sv, Zc, Bd, Sr, Mh, Kt, Ky, Ku The NME uses a standard setup with 1024 Mbps. The schedule consists of long integrations on calibrators J1751+0939, J1801+4404, and J2148+0657 for ftp-fringe tests; The following ftp-fringe tests are scheduled throughout the experiment (1024 Mbps): 12:15:00 (scan 2, 4 sec, J1751+0939) 12:45:00 (scan 4, 4 sec, J1751+0939) 13:15:00 (scan 6, 4 sec, J1751+0939) 13:45:00 (scan 8, 4 sec, J1751+0939) 14:15:00 (scan 10, 4 sec, J1801+4404) -- the source is expected to be resolved on long baselines; Zc is down for this one. 14:45:00 (scan 12, 4 sec, J2148+0657) -- check of long baseline fringes; Ef is down. Good luck with the session!
