INT 204-108 / K04108 correlator report 2004 April 17 108/07:30-108/08:48 Tsukuba correlator, Japan Takashi Nishino, GSI/SED Co., Ltd. Station Comments ---------------- TSUKUB32(T/Ts): All scans had low amplitude in channel S1 (freqs. 2227.99). All scans were processed with 8 or 9 quality codes. Wettzell(V/Wz): All scans were processed with 8 or 9 quality codes. Error rate was a little higher on head "C" during playback. With the problem of ACU, scans at 108-0740 with source 0804+499 was behind in the observation for 13 seconds. However, the result of the correlation was good.
