INT 204-304 / K04304 correlator report 2004 October 30 304/07:30-304/08:32 Tsukuba correlator, Japan Kyoichi Sakamoto, GSI/SED Co., Ltd. Station Comments ---------------- Weighted RMS was a little worse. All scans had low fringe level in channel S2 (freq. 2240.99) and S5 (freq. 2244.99). TSUKUB32(T/Ts): All scans had low p-cal amplitude in the following channels. - X5 (freq. 8732.99) - S1 (freq. 2232.99) - S2 (freq. 2240.99) - S6 (freq. 2352.99) Used manual p-cal for all scans at X/S band in fringe fitting. S5 (freq. 2344.99) was excluded for some scans in fringe fitting. WETTZELL(V/Wz): Error rate was higher on head "C" during playback.
