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!
