INT 205-142 / K05142 correlator report 2005 May 22 142/07:30-142/08:30 Tsukuba correlator, Japan Kentarou Nozawa, GSI/AES Co.,Ltd. Station Comments ---------------- This is an eVLBI intensive session with Tsukuba and Wettzell. The data were recorded with K5(Tsukuba)/Mark5(Wettzell) and transferred from Wettzell to Tsukuba via network. Data transfer from Wz to the Correlator was completed on May 23. Correlation on May 25. There were one or two 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. TSUKUB32(T-Ts): No particular issues to report. Wettzell(V-Wz): No particular issues to report PF=1.0 Station Clocks -------------- Clocks: GSI Station fmout-gps used rate Comments [usec] [usec] [sec/sec] Ts 0.25 0.0 0.0 Reference Wz -15.19 -16.28 -2.96e-12 Date: 2005/05/22 (comment: K5 correlator can not specify any clock offset for reference station.)
