Tsukuba Correlator Report for JD1001 CORREL GSI DATABASE 10JAN14XF SESSNAME JD1001 OBSTIME 2010/1/14 2010/1/15 DOY 014/015 CORRTIME 2010/1/19 2010/1/27 CORRPASS 4 EXPORT DONE CORRELATOR_NOTES ---------------- QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 87.5 % 95.4 % 0 3.9 % 4.3 % 4-1,D,G,N 0.3 % 0.3 % Removed 8.3 % STATION_NOTES: -------------- TSUKUB32(T-Ts): Low pcal amplitude in SR1U caused a D-code on scan 014/20:55. Manual pcal in fringe fitting. Recorded on K5(VSSP32). AIRA (A-Ai): Some scans produced zero codes on X,S-band from 014/02:00 to 014/05:30 due to some snowfall on the antenna. Recorded on K5(VSSP32). CHICHI10(C-Cc): Weather measuring instruments were broken, then the weather data from The Meteorological Agency were added to the log-file. Recorded on K5(VSSP32). SINTOTU3(J-S3): Some scans produced zero codes on X,S-band due to some snowfall on the antenna. Recorded on K5(VSSP32). VERAISGK(S-Vs): Missed 41scans (from 014/02:00 to 014/07:49) because the observation start was delayed. Pcal phases in X,S-band were unstable. Low pcal amplitude in XR3U caused a D-code on scan 014/08:40. Manual pcal in fringe fitting. No cable calibration, because there is not a delay calibrator. Recorded on K5(VSSP32). VERAMZSW(M-Vm): Low pcal amplitude in X-band caused D-codes for 80% of all scans. Manual pcal in fringe fitting. No cable calibrator,because there is not a delay calibrator. Recorded on K5(VSSP32). Note: SINTOTU3 was not included in IVS original master file. It participated in this session as extended mode for a winter observation test.
