XY_MAP /NOGRID

            MAP\XY_MAP [Filename] /NOGRID

        XY_MAP /NOGRID builds an LMV spectra cube and an associated weight image
        from an XY table, but does not regrid the data with a convolution.

        The command checks that it encounters points which are regularly  spaced
        (i.e.,  on  a grid), and it deduces from these the typical parameters of
        the spatial grid (pixel size, map size,  ...).  The  grid  alignment  is
        checked  with  a  tolerance.  By default the tolerance is a tenth of the
        beam, if the beam is known (see HELP XY_MAP TUNING for the possible ways
        to declare the beam). If the beam is not known, the tolerance can be ex-
        plicitly set in the variable MAP%TOLE (in arcsec).

        The parameters of the output cube can  still  be  overridden  by  user's
        MAP%LIKE and MAP% objects.
