Station Comments
----------------
Intensive eVLBI session with TSUKUB32,WETTZELL and ONSALA60.
Recorded Data on Mark5 at WETTZELL and ONSALA60 were transferred
to Tsukuba Correlator via network. 
Converting Mark5 data into K5 form at Tsukuba Correlator. 
Processed on K5 correlation system.

TSUKUB32(U-Ts): OK
		Recorded on K5.

WETTZELL(V-Wz): The temperature data values were not correct 
		during this session, so these values were corrected as
		20.0 degree centigrade. 
	        Recorded on Mark5.

PF=0.5
