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

TSUKUB32(T-Ts): There were errors in the time of the header data
                of S1-S4ch in scan 073/07:35,07:38,08:01,08:06,
                08:09,08:16 and 08:18.
                These scans are not included in this primary solution.
                Recorded on K5(VSSP32). 

WETTZELL(V-Wz): The value of "fmout-gps" has changed from -13sec to -20usec.
                The value of rate was large for -14E-12 sec/sec.
                (This value was calculated from the value of the log file.) 
                Recorded on Mark5.

It is maybe because the rate value of WETTZELL is large as the cause that
the error value of this dUT1 grew. 

- 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.
