INT 205-205 / K05205 Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: July 24, 2005 doy205/07:30-205/08:30 Correlated: July 27, 2005 Exported: done Station Comments ---------------- Intensive eVLBI session with TSUKUB32 and ONSALA60. Recorded Data on Mark5 at ONSALA60 were transferred to Tsukuba Correlator via network. Converting Mark5 data into K5 form at Tsukuba Correlator. Data transfer from On to the Correlator was completed on Julay 25. Correlation on July 27. There were one days until converting Mark5 to K5 was finished due to misinterpretation that number of X2-X8 and S1-S6 were not put properly in a channel list for conversion program. Processed on K5 correlation system. TSUKUB32(U-Ts): OK Recorded on K5. ONSALA60(T-On): OK Recorded on Mark5.
