Tsukuba Correlator Report for K10198 OBSTIME 2010/07/17 DOY 198 CORRTIME 2010/07/17 EXPORT DONE CORRELATOR_NOTES ---------------- All scans were correlated. The X-band SNR were low, because the compressor of LNA of X band of TSUKUB32 stopped. QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 100.0 % 100.0 % 0 0.0 % 0.0 % 4-1,D,G,N 0.0 % 0.0 % Removed 0 % STATION_NOTES ------------- TSUKUB32(T-Ts): The compressor of LNA of X band stopped. WETTZELL(V-Wz): OK. Transfer rate: 256 Mbit/s WETTZELL data were real-time transferred to Tsukuba by data transfer software "VDIF/SUDP".
