Dear Herbert,
I get a strange result with the function \psGaussI: the limit value for x toward infinity is not one. Moreover, the limit value depends on sigma and changing mue does not shift the curve.
Here is my example
\psset{llx=-1.5cm,lly=-1cm,urx=1.5cm,ury=0.5cm,xAxisLabel={$\xi$},yAxisLabel={}}
\scriptsize
\begin{psgraph*}[labels=all,ticks=all,subticks=10]{->}(0,0)(-5,0)(5,1.1){6cm}{3cm}
\psGaussI[linewidth=1pt,mue=0,sigma=1,Simpson=50]{-5}{5}
\psplot[linecolor=blue]{-5}{5}{-10 x /t {t 0 1 GAUSS} 0.01 SIMPSON}
%\psplot{0}{10}{-10 x /t {t dup mul neg 2 div Euler exch exp} 0.01 SIMPSON 2 Pi mul 1 exch div sqrt mul}
\end{psgraph*}
