Code: N22Q1 Schedule Version: 3.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: Benito Marcote Address: JIVE Oude Hoogeveensedijk 4 7991PD Dwingeloo The Netherlands Phone: +31 521 596 508 EMAIL: marcote@jive.eu Fax: Phone during observation: +31 521 596 508 Observing mode: Notes: 0.7 cm (Q-band) ftp fringe test for session 1/2022 (2048 Mbps, L+R, 2-bit sampling, 16 x 32 MHz filters) Please send the disk pack by express to JIVE, NO PCAL Please DO NOT use the phase cal signal. COVER LETTER: This is the schedule for the 0.7 cm Q-band fringe test on 16th March 2022 involving 9 telescopes: Ef Nt On60 T6 Ur Mh Ys Kt Ky Ku. The NME uses a standard setup at 2048 Mbps. The schedule consists of long integrations on strong calibrators J0205+3212 and J0530+1331. Short 1-min scans are interleaved to test the phase-referencing of the EVN data on nearby sources. 4-s ftp-fringe tests are scheduled every 20 and 30 min throughout the experiment: 11:10:00 scan 02 - J0205+3212 11:30:00 scan 06 - J0205+3212 12:00:00 scan 10 - J0205+3212 12:30:00 scan 14 - J0205+3212 13:00:00 scan 19 - J0530+1331 13:30:00 scan 23 - J0530+1331 13:58:00 scan 27 - J0530+1331 And then the session is over!
