INT 204-325 / K04325 correlator report 2004 November 20 325/07:30-325/08:29 Tsukuba correlator, Japan Kyoichi Sakamoto, GSI/SED Co., Ltd. Station Comments ---------------- 1538+149(325/07:42) was not adapted in an analyze, because of the antenna pointing error in Wettzell. 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 S band in fringe fitting. S5 was excluded for all scans in fringe fitting. WETTZELL(V/Wz): Error rate was higher on head "C" during playback.
