JADE-0807(JD0807) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 24 Jul., to 25 Jul., 2008 doy206/02:00 - 207/01:55 Correlated: 29 Jul., 2008 to 12 Aug., 2008 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): Low pcal amplitude in S1ch causing D code in scan 206/10:06. Manual pcal in fringe fitting. Recorded on K5(VSSP32). AIRA (A-Ai): OK Recorded on K5. CHICHI10(C-Cc): Low pcal amplitude in X-band in all scans. Manual pcal in fringe fitting. Recorded on K5. SINTOTU3(J-S3): Low pcal amplitude in S5ch causing D code in scan 206/18:21. Manual pcal in fringe fitting. The fmout-gps vlaue is not correct. The hydrogen maser room rose, and the rate of the hydrogen maser shifted. The offset has shifted though the rate was corrected. Recorded on K5. VERAMZSW(M-Vm): Occasionally slow slew to lock source. 1 scan (206/22:48) out of antenna elevation limit. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): Occasionally slow slew to lock source. No cable calibration from no delay calibrator at VERAISGK. Recorded on K5.
