COVER INFORMATION Station: HART (Code Hh ) Experiment: 3.6cm NME and ftp fringe-test experiment Exp. Code: N11X1 Schedule Version: 1.00 Processed by SCHED version: 9.30 Release near March 23, 2010 PI: Jun Yang Address: JIVE Postbus 2, 7990 AA Dwingeloo The Netherlands Phone: +31 521 596 507 EMAIL: yang@jive.nl Fax: +353 91 750501 Phone during observation: Observing mode: (1) 512-16-2, RCP & LCP. (2) 1024-16-2, RCP only. Notes: See my cover letter. COVER LETTER: Dear EVN friends, N11X1 is 3.6cm (8.4GHz) NME and ftp fringe-test experiment. (1) Make sure that your auto-ftp setting is OK, please. (2) A test mode is used in last scan. The mode is: 1024 Mbps, RCP ONLY,8 BBCs, USB & LSB, 16 MHz filter, 2 bit sampling. Before the scan, I leave a long gap for ONSALA60 to insert attenuators for several BBCs. Furthermore, ZELENCHK and SVETLOE need to reconnect IF cables. (3) Note that the next user experiment EM085 will use both RCP and LCP to observe at 1 Gbps recording rate. If you reconnect IF cables because of the above test mode, you may need to get them back after N11X1. (4) The Kunming 40m radio telescope will participate in N11X1 to test its MK4 backend. Via the backend donated by the Westerbork Observatory and a new MK5B recorder, the new Chinese station is fully compatible with the EVN and other VLBI networks now. Four ftp tests are scheduled: ~12:07 UT (scan 1, 2 sec, J0237+2848) ~13:09 UT (scan 7, 2 sec, J0530+1331) ~14:09 UT (scan 13, 2 sec, J0530+1331) ~15:59 UT (scan 18, 2 sec, J0530+1331) See you in skype group chat!
