Definition
This model describes a Gaussian shaped peak on a flat background
with the peak having height of scale centered at \(q_0\) and having a standard deviation of \(\sigma\). The FWHM (full-width half-maximum) is \(2.354 \sigma\).
For 2D data, scattering intensity is calculated in the same way as 1D, where the \(q\) vector is defined as
