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  assumes  that  it  will  encounter  points  which are regularly
    spaced, and that it can deduce from these the typical parameters of  the
    spatial grid (pixel size, map size, ...).

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