JADE-0804(JD0804) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 17 Apr., to 18 Apr., 2008 doy108/02:00 - 109/01:58 Correlated: 30 Apr., 2008 to 13 May., 2008 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): OK Recorded on K5(VSSP32). AIRA (A-Ai): There was no Pcal signal due to the breakdown of the Dcal unit in all scans. Manual pcal in fringe fitting. Recorded on K5. CHICHI10(C-Cc): Missed 10 scans (108/02:00-03:18) due to the power supply of K5 fell. Missed 3 scans (108/03:58-04:07) due to the power supply of disk slot fell. Low pcal amplitude in X-band in all scans. Manual pcal in fringe fitting. Recorded on K5. VERAMZSW(M-Vm): This observation was discontinued from 108/09:24 during 108/14:31 for the RISE observation. 1 scan (108/05:21) out of antenna elevation limit. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): This observation was discontinued from 108/09:24 during 108/14:31 for the RISE observation. 5 scans (108/05:08,17:48,18:02,18:56 and 109/01:21) out of antenna elevation limit to track source due to under skyline. No cable calibration from no delay calibrator at VERAISGK. Recorded on K5.
