Tsukuba Correlator Report for JX1101 CORREL GSI DATABASE 11JAN29XF SESSNAME JX1101 OBSTIME 2011/01/29-2011/01/30 DOY 029/030 CORRTIME 2011/02/08-2011/02/11 CORRPASS 1.5 EXPORT DONE CORRELATOR_NOTES ---------------- Low fringe snr in XR1U/L and XR2U of USUDA64 due to out of the setting range of the video converter. We dropped the XR1U/L and XR2U for the scans of TU,AU and CU. Because the quality of the bandwidth synthesis file including SR6U was low, we dropped the SR6U for the scans of TU,AU and CU. QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 49.0 % 49.8 % 0 0.3 % 0.4 % 4-1,D,G 49.0 % 49.8 % Removed 1.7 % STATION_NOTES: -------------- TSUKUB32(T-Ts): Low pcal amplitude in SR1U at 029-19:20 caused D-codes. Manual phasecal applied at TSUKUB32. AIRA (A-Ai): OK. CHICHI10(C-Cc): Weather measuring instruments were broken, then the weather data from The Meteorological Agency were added to the log-file. USUDA64(U-Ud):Low fringe snr in XR1U/L and XR2U due to out of the setting range of the video converter. We dropped the XR1U/L and XR2U of all scans. Because the quality of the bandwidth synthesis file including SR6U was low, we dropped the SR6U of all scans. Low pcal amplitude of X- and S-band caused D-codes. Manual phasecal applied at USUDA64. No cable calibration, because there is not a delay calibrator. Recorded on K5.
