QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 96.1 % 96.1 % 0 2.7 % 2.7 % 4-1,D,G,N 1.2 % 1.2 % Removed 0 % STATION_NOTES: -------------- TSUKUB32(T-Ts): OK. Recorded on K5(VSSP32). AIRA (A-Ai): OK. Recorded on K5. CHICHI10(C-Cc): The description of "GPS-K5sampler" in the log file was wrong since the adjustment of H-maser was not enough. Recorded on K5. SINTOTU3(J-S3): Occasionally small hunting phenomena happened in elevation direction. Recorded on K5. VERAISGK(S-Vs): Missed 6 scans (from 197/02:00 to 197/02:26) due to the observation start was late. No cable calibration, because there is not a delay calibrator. No LSB, because the video converter has no output channels for LSB. Recorded on K5.
