JADE-0711(JD0711) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 8 Nov. to 9 Nov., 2007 doy312/02:00 - 313/02:01 Correlated: 27 Nov., 2007 to 4 Dec., 2007 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): Unfortunately setup failure by operator with selecting incorrect drudg option in making snap file, causing lack of procedures for running automatic data acquisition on K5/VSSP32. Missed 226 scans (312/02:00-23:35) without knowing that since there were no error massages occured during the session. Started data acquisition on K5/VSSP32 at 312/23:35 recorded safely remaining scans on K5/VSSP32. included remaining correlation data in DB but not analyzed. AIRA (A-Ai): OK Recorded on K5. CHICHI10(C-Cc): Missed 24 scans (312/02:00-04:24) due to the observation start was late. Low pcal amplitude in S5 causing D code in scan from 312/04:35 to 05:12, 19:50, and from 22:09 to 23:12. Manual pcal in fringe fitting. Recorded on K5. SINTOTU3(J-S3): OK Recorded on K5. VERAMZSW(M-Vm): The observation time was limited in about 17 hours (312/05:30-22:46) due to the observation of RISE. Out of antenna elevation limit to track source and slow slew to lock source at 312/15:50. Low pcal amplitude in X6 and X8 causing D code in scan 312/22:38 and 22:46. Manual pcal in fringe fitting. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): The observation time was limited in about 17 hours (312/05:30-22:46) due to the observation of RISE. Missed 10 scans (312/21:37-22:46) in S1-S4. Recorded on K5. No cable calibration from no delay calibrator at VERAISGK. The baseline solved by this session is AC,AM,CM,CS and MS baselines.
