QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 90.7 % 90.7 % 0 7.0 % 7.0 % 4-1,D,G,N 2.3 % 2.3 % Removed 0 % STATION_NOTES ------------- TSUKUB32(T-Ts): OK. WETTZELL(V-Wz): Low amplitude in XR5U caused a D code on scan 073/07:39. Manual pcal in fringe fitting. Transfer rate: 200 Mbit/s WETTZELL data were transferred to Tsukuba by data transfer protocol "Tsunami".
