JADE-0801(JD0801) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 21 Jan., to 22 Jan., 2008 doy021/02:00 - 022/01:53 Correlated: 1 Feb., 2008 to 6 Feb., 2008 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): OK Recorded on K5(VSSP32). AIRA (A-Ai): Missed 5 scans (021/02:00-02:11) in X5-X8 due to the disk exchange. Missed all scans (021/02:00-022/01:53) in S1-S8 due to selecting incorrect S-band frequency in making schedule file. S1-S8 dropped from fring fitting on TA(Ts-Ai) and AC(Ai-Cc) baselines. Recorded on K5. CHICHI10(C-Cc): Low pcal amplitude in S1,2 causing D code in scan 021/07:53. Manual pcal in fringe fitting. Recorded on K5. This primary solution didn't give the ion correction.
