           Define 2-Dim Gaussian fit model y =  1/sqrt(sigma*2*pi)
                                                * exp(
                                                - 0.5*((x_1-x0)/sigma_x)^2
                                                - 0.5*((x_2-y0)/sigma_y)^2)

           x         - 2-Dim Input x value array. Should be double precision.
           parameter - Parameter to compute model. Must contain 2
                       values.

           gauss:x0      - X1-Component of the center of the Gaussian
                           curve (mean value)
           gauss:y0      - X2-Component of the center of the Gaussian
                           curve (mean value)
           gauss:xsigma  - Width of the Gaussian curve in x direction.
           gauss:ysigma  - Width of the Gaussian curve in y direction.
