JADE-0406 correlator report 2004 June 10 162/02:00-163/02:00 Tsukuba correlator, Japan Kyoichi Sakamoto, GSI/SED Co., Ltd. Station Comments ---------------- TSUKUB32(T-Ts): All scans had low amplitude in channel S1 (freqs. 2227.99). Used manual p-cal in S band in the following scans. - 3C274 (162/04:02) - 1923+210(162/10:50) - 3C273B (162/14:27) - 2255+282(162/16:55) AIRA (A-Ai): Insert clock break at UT 162/16:00. The temperature of the front end was not stable. Analyzed result exceed the 5.00 D-14 which was imposed at first, then 7.00 D-14 was finally re-imposed as Clock constraint. Atmosphere was not stable in the influence in the typhoon. Analyzed result exceed the 50.00 ps/h which was imposed at first, then 120.00 ps/h was finally re-imposed as Atmosphere constraint. CHICHI10(C-Cc): The temperature of the front end was not stable. Scans at 1519+273(162/10:59), 1418+546(162/19:05), 2255-282(162/20:06) and 3C454.3 (162/20:33) had drift of p-cal. Scan at 1519+273(162/13:27) had low amplitude in S band channel 1,2,4,6 and 8ch. Scan at 3C454.3(162/20:33) used manual p-cal in S band. Used manual p-cal in X band in the following scans. - 1519+273(162/10:59) - 1519+273(162/13:27) - 1418+546(162/19:05) SINTOTU3(J-S3): Failed to record all scans, because of DMS trouble.
