Arecibo may join after 14:42UT. The NME uses a standard setup with 512 Mbps. The schedule consists of long integrations on calibrators J2031+1219 and J1310+3220 for ftp-fringe tests. The following ftp-fringe tests are scheduled throughout the experiment (UT times): 13:15:00 (scan 2, 2 sec, J2031+1219) 13:35:00 (scan 4, 2 sec, J2031+1219) 14:55:00 (scan 6, 2 sec, J2031+1219) 14:15:00 (scan 8, 2 sec, J2031+1219) 14:35:00 (scan 10, 2 sec, J2031+1219) 14:55:00 (scan 12, 2 sec, J1310+3220) --- Arecibo joins 15:15:00 (scan 14, 2 sec, J1310+3220) 15:35:00 (scan 16, 2 sec, J1310+3220) Good luck with the session!
