Tsukuba Correlator Report for K11058 OBSTIME 2011/2/27 DOY 058 CORRTIME 2011/2/27 EXPORT DONE CORRELATOR_NOTES ---------------- Scans at 058/08:01 caused a zero code on S band. The source being observed was 3C371. QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 98.8 % 98.8 % 0 1.2 % 1.2 % 4-1,D,G,N 0.0 % 0.0 % Removed 0.0 % STATION_NOTES ------------- TSUKUB32(T-Ts): Low pcal amplitude in SR1U caused D codes in scan 058/07:32 and 08:19. Manual Pca in fringe fitting. WETTAELL(V-Vs): OK. Transfer rate: 256 Mbit/s WETTZELL data were real-time transferred to Tsukuba by data transfer software "VDIF/SUDP".
