JADE-0811(JD0811) Correlation report Tsukuba VLBI Correlator [Geographical Survey Institute, Japan] Observed: 13 Nov., to 14 Nov., 2008 doy318/02:00 - 319/01:59 Correlated: 21 Nov., 2008 to 15 Dec., 2008 DB Exported: done Station Notes: -------------- TSUKUB32(T-Ts): Low pcal amplitude in S4,5ch causing D codes in scan 318/15:47,16:06,16:20,16:41,16:56,16:57,17:06 and 17:19. Manual pcal in fringe fitting. Recorded on K5(VSSP32). AIRA (A-Ai): Low pcal amplitude in X3,4,5,6,7,8ch causing D code in scan 319/01:13. Manual pcal in fringe fitting. Recorded on K5. CHICHI10(C-Cc): Missed 44 scans (from 318/02:03 to 318/05:08) due to the making mistake of the parameter file. Low pcal amplitude in X-band in all scans. Manual pcal in fringe fitting. Recorded on K5. SINTOTU3(J-S3): Missed 15 scans (from 318/14:58 to 318/16:08) due to the disk mount error. Recorded on K5. VERAMZSW(M-Vm): Occasionally slow slew to lock source. 1 scan (318/17:53) out of antenna elevation limit. No cable calibration from no delay calibrator at VERAMZSW. Recorded on K5. VERAISGK(S-Vs): Missed all scans in S-band due to a set mistake of the frequency of S-band. Missed 118 sacns in X-band (from 318/16:00 to 319/01:52). Occasionally slow slew to lock source. 2 scans (318/3:58,11:55) out of antenna elevation limit. No cable calibration from no delay calibrator at VERAISGK. Recorded on K5. Date was recorded with 2bit.
