INT 208-257 / K08257 Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: Sep 13, 2008 doy257/07:30-257/08:29 Correlated: Sep 19, 2008 Exported: done Station Comments ---------------- TSUKUB32(T-Ts): OK Recorded on K5(VSSP32). WETTZELL(V-Wz): All scans were observed by using an old schedule file (created August 20). Recorded on Mark5. Lost 1 scan at 257/08:07. The integration time shortened because the schedule used was different since 257/08:10. - comment: 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.
