The source being observed was 1418+546. There was low SNR but good integration time for this scan. +STATION_NOTES KOKEE (K-Kk): OK. Transfer rate: 200 Mbit/s WETTZELL(V-Vs): The meteorological data in log file was abnormal. Station said that some problems in the metsensor readings according to problem in the connector and the wires between acquisition and sensors. The meteorological data were modified. Temperature : -30.0 -> 20.0 Humidity : 0.0 -> 80.0 Transfer rate: 256 Mbit/s KOKEE data were transferred to Tsukuba by data transfer software "TSUNAMI". WETTZELL data were real-time transferred to Tsukuba by data transfer software "VDIF/SUDP". +MANUAL PCAL +CHANNELS XR1U = band|polarization|channel#|sideband XR1U/L BBC01 8182.99 XR2U BBC02 8222.99 XR3U BBC03 8422.99 XR4U BBC04 8562.99 XR5U BBC05 8682.99 XR6U BBC06 8782.99 XR7U BBC07 8842.99 XR8U/L BBC08 8862.99 SR1U BBC09 2212.99 SR2U BBC10 2222.99 SR3U BBC11 2257.99 SR4U BBC12 2297.99 SR5U BBC13 2317.99 SR6U BBC14 2322.99 +DROP_CHANNELS Kk Wz +CLOCKS Clocks: KOKEE Station fmout-gps used rate Comments [usec] [usec] [sec/sec] Kk 4.397 4.397 -13.204E-12 Reference Wz -23.052 -23.737 -8.645E-12 Date: 2011/08/13 +QCODES PROCESS SUMMARY BY BASELINE/FREQUENCY Base 0 1 2 3 4 5 6 7 8 9 D G N - Tot KV X 0 0 0 0 0 0 0 0 5 13 0 0 0 0 18 KV S 1 0 0 0 0 0 0 0 0 17 0 0 0 0 18 Column Totals, numbers then percentages 1 0 0 0 0 0 0 0 5 30 0 0 0 0 36 % 2.8 0.0 0.0 0.0 0.0 0.0 0.0 --> --> 97.2 0.0 0.0 0.0 0.0100.0 QC = 0 : Fringes not detected. = 1-9 : Fringes detected.
