----------------

TSUKUB32(T-Ts): Fmout-gps had shifted 1 second.
                No fringe in group D data(S5,S6,X1L,X8L).
                Recorded on K5(VSSP32). 

WETTZELL(V-Wz): OK
                Recorded on Mark5.
                Reference station. 

- 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.
