Tsukuba Correlator Report for JD1003 CORREL GSI DATABASE 10MAR11XF SESSNAME JD1003 OBSTIME 2010/3/11 2010/3/12 DOY 070/071 CORRTIME 2010/3/17 2010/3/26 CORRPASS 3 EXPORT DONE CORRELATOR_NOTES ---------------- For the baseline CM, fringe fitted without channels SR5U,SR6U,XR1L and XR8L. A HDD,which recorded these channels of Vm, had broken when we correlated CM. QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 99.1 % 99.1 % 0 0.6 % 0.6 % 4-1,D,G,N 0.3 % 0.3 % Removed 0.0 % STATION_NOTES: -------------- TSUKUB32(T-Ts): Low pcal amplitude in SR1U caused D-codes on 6 scans. Manual pcal in fringe fitting. Recorded on K5(VSSP32). AIRA (A-Ai): OK. Recorded on K5. 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. VERAMZSW(M-Vm): Low pcal amplitude in X-band caused D-codes on 21 scans. Manual pcal in fringe fitting. A HDD,which recorded channels SR5U,SR6U,XR1L and XR8L, had broken when we processed CM. Occasionally slow slew to lock source. Pcal phase was unstable in X-band. No cable calibrator,because there is not a delay calibrator. Recorded on K5. Note: VERAISGK was included in IVS original master file. But it couldn't take part in this session, because its antenna had a trouble.
