JADE-0901(JD0901) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 16 Jan., to 17 Jan., 2008 doy016/02:00 - 017/01:59 Correlated: 22 Jan., 2009 to 28 Jan., 2009 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): Low pcal amplitude in S1,2ch in scan 016/02:08 and 19:14. Manual pcal in fringe fitting. Recorded on K5(VSSP32). AIRA (A-Ai): Low pcal amplitude in X-band in ~25 of all scans. Manual pcal in fringe fitting. Recorded on K5. CHICHI10(C-Cc): Low pcal amplitude in X-band in all scans. Manual pcal in fringe fitting. Recorded on K5. VERAMZSW(M-Vm): Low pcal amplitude in X-band in ~50 of all scans. Manual pcal in fringe fitting. No LSB X8ch data and the setting of the video converter bandwidth was 2MHz from 016/02:00 to 13:13. Occasionally slow slew to lock source. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): Occasionally slow slew to lock source. 4 scans (016/2:18,7:04,7:49 and 23:36) out of antenna elevation limit. No LSB X1,8ch data from no LSB output of the video converter. No cable calibration from no delay calibrator at VERAISGK. Recorded on K5. Note: VERAMZSW and VERAISGK which were left out of the original IVS master schedule, participated in this session as extended mode.
