UV_TIME

        [CLEAN]UV_TIME [?|Time] [/Weight Wcol] [/FILE FileIn]

    Average  in  time  the current UV data set to reduce the number of visibili-
    ties.  Time must be in seconds. If not specified, an automatic guess is per-
    formed based on Nyquist  criterium  using  the  antenna  size  and  baseline
    lengths.

    With a ? as argument, return the longest reasonable time.  This time depends
    on the field of view (that can be controlled by MAP_FIELD) and the requested
    precision  (controlled  by  MAP_PRECIS).   It is also limited by the UV cell
    size for beam forming (MAP_UVCELL).
