JADE-0803(JD0803) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 13 Mar., to 14 Mar., 2008 doy073/02:00 - 074/01:59 Correlated: 19 Mar., 2007 to 4 Apr., 2008 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): OK Recorded on K5(VSSP32). AIRA (A-Ai): OK Recorded on K5. CHICHI10(C-Cc): Missed 11 scans (073/05:55-07:07) due to the power supply of K5 fell. Low pcal amplitude in S5 causing D codes in scan 073/19:59-20:12, 21:58-22:01, 22:10-22:23 and 22:33-22:38. Manual pcal in fringe fitting. Recorded on K5. VERAMZSW(M-Vm): 1 scan (073/10:02) out of antenna elevation limit. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): Missed 135 scans (073/02:00-19:03) due to the station coordinates of the vex schedule were mistaken. Recorded on K5. No cable calibration from no delay calibrator at VERAISGK.
