Scan at 330-0826 produced a zero code on S band.
The source being observed was NGC6251.
There was low SNR but good integration time for these scan.


+STATION_NOTES

TSUKUB32(T-Ts): No fringe in channels XR5U, X6RU, XR7U and XR8U/L
                due to the setting mistake of the ADS3000+.
                Channels removed from fringe fitting.
                Recorded on ADS3000+.

WETTZELL(V-Vs): OK.
                Transfer rate: 256 Mbit/s

WETTZELL data were real-time transferred to Tsukuba by 
data transfer software "VDIF/SUDP".
