+CORRELATOR_NOTES
Scan at 309-0735 produced a zero code on S band.
The source being observed was 0800+618.
There was low SNR but good integration time for this scan.
+STATION_NOTES
TSUKUB32(T-Ts): Low pcal amplitude in SR1U, SR2U and SR3U at 309-0735 UT
and SR1U at 309-0735 UT caused D codes on S-band.
Manual phasecal applied at WETTZELL.
WETTZELL(V-Wz): OK.
Transfer rate: 256 Mbit/s
WETTZELL data were real-time transferred to Tsukuba by
data transfer software "VDIF/SUDP".
