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.

TSUKUB32(T-Ts): Setup failure of attaching time tag
                by one second late to all scans.
		Fringed by correcting the time tag.
                Recorded on K5.

WETTZELL(V-Wz): Unstable pcal phases in scans 176/07:30
                and 07:33 causing G-codes: scan 176/07:30
		was removed from fringe fitting.
                Recorded on Mark5.
