Workspace Method backend_channel_responseGaussian

Description

Sets up a gaussian backend channel response.

The method assumes that all channels can be modelled as gaussian.

If *fwhm* has only one element, all channels are assumed to be equal.
If *fwhm* has multiple elements, *xwidth_si* and *dx_si* must have one
element or the same number of elements as *fwhm*. If one element is given,
this value will be used for all channels.

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*).
