TSUKUB32(T-Ts): OK.
                Recorded on K5.

SINTOTU3(J-S3): Missed 115 scans from 321/14:03 to 321/23:38 due to FS trouble.
                FS couldn't get weather data from weather measuring instruments,
                then weather data from The Meteorological Agency were added to 
                the log-file.
                Recorded on K5.
                Low pcal amplitude in S-band at 321/03:16, 04:13, 04:57, 05:31
                and 09:55 caused D codes.
                Manual phasecal applied.
