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.
