JADE-0906(JD0906) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 11 Jun., to 12 Jun., 2009 doy162/02:00 - 163/01:55 Correlated: 23 Jun., 2009 to 29 Jun., 2009 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): Low pcal amplitude in S1 caused a D-code on scan 162/13:45. Manual pcal in fringe fitting. Recorded on K5(VSSP32). AIRA (A-Ai): Lost 31 scans (from 162/02:02 to 162/04:30) only for AC-baseline due to a HDD trouble. The X5-8 data for them broke. Recorded on K5. CHICHI10(C-Cc): The description of "GPS-K5sampler" in the log file was wrong since the adjustment of H-maser was not enough. Recorded on K5. SINTOTU3(J-S3): Low pcal amplitude in X-band caused D-codes on scan 162/22:41 and 163/01:01. Manual pcal in fringe fitting. Occasionally hunting phenomina happend ( from 162/16:28 to 163/01:38) in azimuth direction. Recorded on K5. VERAISGK(S-Vs): Missed 8 scans (from 162/02:00 to 162/02:18) due to the observation start was late. 7 scnas (162/03:07, 162/05:14, 162/08:28, 162/14:05, 162/14:41,162/16:40 and 163/01:34 ) were out of antenna elevation limit due to under skyline. No cable calibration from no delay calibrator at VERAISGK. Recorded on K5. Note: VERAISGK which were left out of the original IVS master schedule, partcipated in this session as extended mode.
