JPNTI7 database : created by Y. Koyama (CRL/Kashima).
The experiment was performed with 6 VLBI stations in Japan.
These stations are Kashima (26m), Kashim34, Kashim11, Koganei,
Tateyama, and Tsukuba32. Observatin data rate was 128 Mbps
(8Mbps X 16ch.) and the K4 VLBI data acquisition terminal
was used. The data were correlated at Kashima by using the
KSP correlator system.

3rd ch. and 9th ch. at Kashima station were not recorded
because the K4 type 1 Video Converter system was used at
the station. About half of the data recorded at Kashim11
station were missed because the tape was recorded
continuously without stopping and the tapes reached to the
end well before the tape changes. Because of this problem,
about half of the scan for the Kashim11-Kashima,
Kashim11-Kashim34, and Kashim11-Tsukub32 baselines are
not available. However, the other baselines including
Kashim11 station (i.e. Kashim11-Koganei and Kashim11-Tateyama)
were not affected because these baselines were processes
with the real-time correlator.

Kashim34 station suffered a phase variation problem and the
RMS for the Kashim34 related baselines are quite large compared
with the other baselines. The H-mase frequency at Kashim34 and
Kashima station were shifted their frequency to separate the
fringe and P-cal correlatin.
