+CORRELATOR_NOTES

Scan at 301-0825 produced a zero code on X band.
The source being observed was 1739+522.
There was low SNR but good integration time for this scan.


+STATION_NOTES

KOKEE   (K-Kk): OK.
                Transfer rate: 200 Mbit/s

WETTZELL(V-Wz): Low pcal amplitude in XR3U and SR3U at 301-0732 UT caused D codes on X,S-band.
                Manual phasecal applied at WETTZELL.
                Transfer rate: 256 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 "VDIF/SUDP".
