    When  reading  UV  Tables, ignores any trailing column. Trailing columns
    normally appear for mosaics. However, ALMA sometimes uses  known  proper
    motions  to shift (by small amounts) phase centers between two observing
    periods, yielding pseudo-mosaics with tiny  (in  general  insignificant)
    displacements.  The /NOTRAIL option allows to ignore these details.
