INT 206-056 / K06056 Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: February 25, 2006 doy056/07:30-056/08:30 Correlated: February 27, 2006 Exported: done Station Comments ---------------- Intensive eVLBI session with TSUKUB32 and WETTZELL. Recorded Data on Mark5 at WETTZELL were transferred to Tsukuba Correlator via network. Converting Mark5 data into K5 form at Tsukuba Correlator. Processed on K5 correlation system. No fringe on X-band of 1 scan:056/08:26 which came from 2318+049. The value of W.RMS of source 2318+049 was large. TSUKUB32(T-Ts): OK Recorded on K5. WETTZELL(V-Wz): OK Recorded on Mark5.
