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!
