Workspace Method backend_channel_responseGaussian

Description

Sets up a gaussian backend channel response.

The method assumes that all channels have the same response, and
that it can be modelled as gaussian.

The grid generated can be written as
   si * [-xwidth_si:dx_si:xwidth_si]
where si is the standard deviation corresponding to the FWHM.
That is, width and spacing of the grid is specified in terms of
number of standard deviations. If xwidth_si is set to 2, the
response will cover about 95% the complete response. For
xwidth_si=3, about 99% is covered. If xwidth_si/dx_si is not
an integer, the end points of the grid are kept and the spacing
if the grid is adjusted in the downward direction (ie. spacing is.
is max *dx_si*).
