JADE-0709(JD0709) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 13 Sep. to 14 Sep., 2007 doy256/02:00 - 257/02:02 Correlated: 28 Sep., 2007 to 19 Oct., 2007 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): OK Recorded on K5(VSSP32). AIRA (A-Ai): Missed 14 scans (from 256/10:48 to 256/11:47) in X5-X8 due to the OS of recorder was hung up. Low pcal amplitude in S1 and S5 causing D codes in scan 256/06:06, 256/09:16 and 256/10:29. Low pcal amplitude in X1 causing D codes in scan 256/04:14 and 256/12:31. Manual pcal in fringe fitting. Recorded on K5. CHICHI10(C-Cc): OK Recorded on K5. SINTOTU3(J-S3): OK Recorded on K5. VERAMZSW(M-Vm): Out of antenna elevation limit to track source at 256/18:20, 256/19:31 and 256/23:52. Slow slew to lock source at 256/08:39 and 256/13:22. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): Missed 6 scans (from 256/02:00 to 256/02:30) due to the observation start was late. Missed 2 scans (from 256/05:27 to 256/05:41) due to autoobs stopped. -1sec of clock offset discrepancy between group B(X5-X8) and another groups A, C, D(X1-X4,S1-S8). Baselines of Ts-Vs, Ai-Vs, Cc-Vs and Vs-Vm were fringe-fitted by setting relative clock offfset(this is an option of K5 correlation package which controls clock offset discrepancy handling). No cable calibration from no delay calibrator at VERAISGK. Recorded on K5.
