Code: N13X3 Schedule Version: 2.00 Processed by SCHED version: 10.20 Release of about July 12, 2012 PI: Jun YANG Address: JIVE Postbus 2 7990 AA Dwingeloo The Netherlands Phone: +31-521-596507 EMAIL: yang@jive.nl Fax: Phone during observation: +31-521-596507 Observing mode: Notes: 3.6cm NME for session 2/2013 512 Mbps, 2-bit sampling, 8 MHz filters N13X2 was cancelled. F13X1 was replaced by N13X3 COVER LETTER: Three ftp tests are scheduled: 09:04:00 UT (scan 2, 1 sec, DA193) 10:09:00 UT (scan 8, 2 sec, 4C39.25) 10:49:00 UT (scan 12, 2 sec, 4C39.25) Please make sure that the autoftp is set up correctly. Version 2 removed one scan of DA193 and added 5 scans for a test of VEX observations. Good luck with the session!
