+CORRELATOR_NOTES

Scan at 063-0618, 063-0634 and 063-0646 produced a zero codes on S band.
The source being observed were 0716+714.
There were low SNR but good integration time for these scans.


+STATION_NOTES

KOKEE   (K-Kk): Low pcal ampulitude in SR5U causing D code
                in scan 063-0653.
                Manual pcal applied.
                Transfer rate: 200 Mbit/s

WETTZELL(V-Vs): OK.
                Transfer rate: 300 Mbit/s

KOKEE data were transferred to Tsukuba by 
data transfer software "TSUNAMI".
WETTZELL data were real-time transferred to Tsukuba by 
data transfer software "TSUNAMI".
