        SHOW COVERAGE [Ant [Date]]

    Displays the UV coverage.  Ant and Date are  optional  arguments  indicating
    which Antenna is to be highlighted, and for which date. Date is a sequential
    number from 1 to the number of observing dates.

    For  spectral  line UV data, SHOW COVERAGE will only show one UV coverage if
    FIRST and LAST are set to zero. It will show one per channel otherwise.
