Station Comments
----------------

TSUKUB32(T-Ts): Low pcal amplitude in S2 causing D code
                in scan 174/08:06.
                Manual pcal in fringe fitting.
                Recorded on K5(VSSP32). 

WETTZELL(V-Wz): Missed 14 scans (from 174/07:30-174/07:52)
                due to the observation start was late.
                Because of problems with automatic observation mode.  
                Recorded on Mark5.

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.
