JADE-0905(JD0905) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 21 May., to 22 May., 2009 doy141/02:00 - 142/01:56 Correlated: 29 May., 2009 to 09 Jun., 2009 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): OK Recorded on K5(VSSP32). AIRA (A-Ai): The description of "GPS-K5sampler" in the log file was wrong since there was some trouble with the counter due to too weak 1-pps signal of H-maser. Recorded on K5. CHICHI10(C-Cc): Low pcal amplitude in X-band caused D-codes in all scans. Manual pcal in fringe fitting. The value of "GPS - K5sampler" was about 9000 nsec since the H-maser had been reactivated immediately before this session. Recorded on K5. SINTOTU3(J-S3): Missed 4 scans (from 141/02:00 to 141/02:32) in S1-S4 due to a trouble of the reacorder. Low pcal amplitude in X-band caused a D-code in scan 141/20:25. Manual pcal in fringe fitting. Occasionally hunting phenomina happend ( from 141/14:26 to 141/16:01 and 141/19:17 to 142/02:00) in azimuth direction. Recorded on K5. VERAMZSW(M-Vm): Missed 5 scans (from 141/02:00 to 141/02:33) due to the start was late at. Occasionally slow slew to lock sources. 1 scan (141/21:38) out of antenna elevation limit. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): Missed 4 scans (from 141/02:00 to 141/02:32) in X5-X8 due to the OS of the recorder hung up. Occasionally slow slew to lock sources. 5 scnas (141/06:26, 141/10:19, 141/18:08, 141/12:57 and 141/23:23) out of antenna elevation limit due to under slyline. No cable calibration from no delay calibrator at VERAISGK. Recorded on K5. Note: VARAMZSW and VERAISGK which were left out of the original IVS master schedule, partcipated in this session as extended mode.
