gsmooth(data [[, axis], width, /normalize,
/fullnorm, /balanced, /all])
Returns a smoothed version of
data, with a gaussian
smoothing kernel with a FWHM of
width elements along axes
have more than one element, in which case multiple smoothing passes are
performed using subsequent values of these arguments.
/fullnorm specifies that the weighted sum of data values
is always normalized with the full sum of weights in the kernel: it adds
in data values beyond the edges of
data as zeros.
/balanced reduces the width of the included data set so
that the weighted and included data is always balanced around the
central point: in this way, a smoothed version of a straight line is
also a straight line.
/all specifies that all axes must be smoothed along, but
is ignored if
axis is specified.
