After the calibration update work (klog#34088), line tracking parameters were updated. They are accepted in observation.snap (Fig.1), down.snap (Fig.2), and safe.snap (Fig.3). On down.snap and safe.snap, measurement date record also accepted. (Keeping these values is enough when model is restarted, so it can be set as CHANS_NOT_MON on down.snap.) And then, numerical residuals on observation.snap were reverted (Fig.4).
