CORRELATOR_NOTES
----------------
No Ts data in SR5U, SR6U, XR1L and XR8L due to HDD trouble of K5system.
SR5U,SR6U,XR1L and XR8L were dropped from fringe fitting in all scans.
Scan at 241/07:32 produced a zero code on X band and S band.
The source being observed was OQ208.

STATION_NOTES
-------------
TSUKUB32(T-Ts): No Ts data in SR5U, SR6U, XR1L and XR8L.
                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".
