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

\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}
