CORRELATOR_NOTES
----------------
All scans were fine.
But the X-band SNR were small,
because the X-band noise of TSUKUB32 was large.

STATION_NOTES
-------------
TSUKUB32(T-Ts): The X-band noise was large, 
                because the X-LNA cryogenic system was in bad condition.
               
WETTZELL(V-Wz): OK.
                Transfer rate: 200 Mbit/s

WETTZELL data were transferred to Tsukuba by 
data transfer protocol "Tsunami".
