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).
