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

SINTOTU3(J-S3) : Missed 32 scans of SR5U, SR6U, XR1L and XR8L
                 from 138/02:00 UT to 138/04:49 UT due to hard-disk trouble.
                 FS couldn't get meteorological data, because of weather 
                 measureing instruments trouble. So, meteorological data
                 from The Meteorological Agency were added to the log-file.
                 Recorded on K5.
                 Low pcal amplitude in XR1U on 139/00:34 UT caused D code.
                 Manual phasecal applied.
