Tsukuba Correlator Report for JD1101 CORREL GSI DATABASE 11JAN13XF SESSNAME JD1101 OBSTIME 2011/01/13-2011/01/14 DOY 013/014 CORRTIME 2011/01/25-2011/02/01 CORRPASS 4.0 EXPORT DONE CORRELATOR_NOTES ---------------- Some XR1U/L data of CHICHI10 were broken. We drop the XR1U/L channels for the scans of TC,AC,CM and CS. QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 90.9 % 96.6 % 0 0.4 % 0.4 % 4-1,D,G 2.9 % 3.0 % Removed 5.8 % STATION_NOTES: -------------- TSUKUB32(T-Ts): Low pcal amplitude in SR1U caused D-codes. Manual pcal in fringe fitting. Recorded on K5(VSSP32). AIRA (A-Ai): "fmout-GPS" descriptions in the log-file were not correct. Recorded on K5(VSSP32). CHICHI10(C-Cc): Missed 37scans from 013/16:57 to 013/19:53 due to K5-system trouble. Ocassionary XR1U/L data were broken. We drop the XR1U/L channels for the scans. Weather measuring instruments were broken, then the weather data from The Meteorological Agency were added to the log-file. Recorded on K5(VSSP32). VERAMZSW(M-Vm):Pcal signals in X-band were not good. The amplitude were low and phases were unstable. Manual pcal in fringe fitting. No cable calibration, because there is not a delay calibrator. Recorded on K5(VSSP32). VERAIAGK(S-Vs):OK. No cable calibration, because there is not a delay calibrator. Recorded on K5(VSSP32).
