XY_SHORT

        [ADVANCED\]XY_SHORT [Arg]

    Compute  the  Short  Spacings  image  from the current "Single Dish" dataset
    (read by READ SINGLE) when this dataset is a Class table, and make it avail-
    able as the SHORT image variable.

      If the "Single Dish" dataset is already a 3-D data cube, nothing  is  done
    as it is alreay accessible through the SHORT image variable.

    XY_SHORT  uses  the  same  input  parameters  as UV_SHORT. It corresponds to
    Step_1 of UV_SHORT.
