JADE-0310 correlator report 2003 November 12 316/02:00-317/02:02 Tsukuba correlator, Japan Kyoichi Sakamoto, GSI/SED Co., Ltd. Station Comments ---------------- TSUKUB32(T-Ts): Error rate level of recorder head B and D were higher during playback. AIRA (A-Ai): No particular issues to report. CHICHI10(C-Cc): Obs No.133 was processed with fluctuating p-cal, which a stain on the tape surface is likely. SINTOTU3(J-S3): No particular issues to report. VERAMZSW(M-Vm): No fringe were shown in channel "16"(freqs. 2354.99) in S-band during all scans, and processed excluding the channel. Because p-cal phase fluctuation was seen on the S-band from UT 316/17:07, it processed by manual p-cal. GIFU11 (Y-Gu): It confirmed the clock break of nearly 1 ns. There might be any problems in the sampler of K4, video converter or hydrogen maser. Inserted clock breaks at UT 316/05:20 and 07:25.
