March 14, 2015 PI: Benito Marcote Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596508 EMAIL: marcote@jive.eu Fax: Phone during observation: +31-521-596508 Observing mode: Notes: 6cm NME and ftp fringe test for session 3/2017 with 2 modes (512 and 2048 Mbps, L+R, 2-bit sampling, 8 and 32 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 6cm NME and ftp fringe-test on 25 October 2017 involving antennas: Jb2, Wb, Ef, Mc, Nt, On85, T6, Ur, Tr, Ys, Sv, Zc, Bd, Hh, Ir, Nk, and MERLIN outstations. The NME uses a standard setup with 512 Mbps during the first 2 hr. The NME uses a standard setup with 2048 Mbps during the last hr (Jb 2Gb). The schedule consists of: - long integrations on calibrator J1848+3219 for ftp-fringe tests; Strong fringes were found in N16C3 on this source. The following ftp-fringe tests are scheduled throughout the experiment (512 Mbps): 12:15:00 (scan 2, 2 sec, J1848+3219) 12:45:00 (scan 6, 2 sec, J1848+3219) 13:15:00 (scan 10, 2 sec, J1848+3219) 13:45:00 (scan 14, 2 sec, J1848+3219) Change to 2048 Mbps setup. 14:10:00 (scan 17, 2 sec, J1848+3219) 14:30:00 (scan 19, 2 sec, J1848+3219) 14:50:00 (scan 21, 2 sec, J1848+3219) Good luck with the session!
