+CORRELATOR_NOTES
The clocks of SR1U, SR2U, SR3U and SR4U shifted 1 sec.
Processed in primary solution without S-band because the group ionosphere calibration
was not able to be resolved.

+STATION_NOTES

TSUKUB32(T-Ts): Missed 2 scans from 139/02:02 and 139/02:07.

SINTOTU3(J-S3): Missed 2 scans from 139/02:02 and 139/02:07.
                Low pcal amplitude in XR1U causing D code in scan 139/16:59.
                Manual pcal in fringe fitting.
