JADE-0710(JD0710) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 18 Oct. to 19 Oct., 2007 doy291/02:00 - 292/01:56 Correlated: 26 Oct., 2007 to 22 Nov., 2007 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): No fringe 4scans (291/02:00, 06:45, 22:57 and 292/00:43) in S5-S8 due to data bit error. Recorded on K5(VSSP32). AIRA (A-Ai): Low pcal amplitude in S1 and S2 causing D code in scan 291/09:55. Manual pcal in fringe fitting. Recorded on K5. CHICHI10(C-Cc): The air condition was not stable in receiver room. Recorded on K5. SINTOTU3(J-S3): Missed 2 scans (291/02:00 and 291/02:02) due to the observation start was late. Low pcal amplitude in S6 causing D code in scan 291/06:45. Manual pcal in fringe fitting. Recorded on K5. VERAMZSW(M-Vm): Missed 1 scan 292/01:28 due to not tracking. Due to slow slew. 2 scans (291/11:20 and 291/11:45) out of antenna elevation limit to track source due to masked by 10m antenna. Slow slew to lock source at 291/02:12. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): Miseed all scans. Failed to remote control due to disconnection of cablenetwork.
