Tsukuba Correlator Report for JD1006 CORREL GSI DATABASE 10JUN22XF SESSNAME JD1006 OBSTIME 2010/6/22 2010/6/23 DOY 173/174 CORRTIME 2010/6/29 2010/7/8 CORRPASS 3.4 EXPORT DONE CORRELATOR_NOTES ---------------- For the baseline TC, scan at 173/19:14 was not correlated. Because the XR1-4U data of CHICHI10 was broken. QUALITY SUMMARY --------------- Qcode % of Total % of Correlated scans scans 5-9 90.3 % 90.3 % 0 9.0 % 9.0 % 4-1,D,G,N 0.7 % 0.7 % Removed 0.0 % STATION_NOTES: -------------- TSUKUB32(T-Ts): Low pcal amplitude in SR1U caused D-codes in scan 174/03:29,04:04,10:07 and 13:22. Manual pcal in fringe fitting. Recorded on K5(VSSP32). AIRA (A-Ai): Pcal signal in X-band was not good because the dcal unit didn't work well. Its amplitude was low and phase was unstable. Manual pcal in fringe fitting. Recorded on K5(VSSP). CHICHI10(C-Cc): OK. Recorded on K5(VSSP). SHINTOTU3(J-S3):Low pcal amplitude in XR1U caused D-codes in scan 173/18:55 and 174/05:59. Manual pcal in fringe fitting. Recorded on K5(VSSP).
