In that case you might want to try peak-o-mat (lorentz.sf.net) which does curve
fitting based on the scipy.sandbox.odr module. The odr module is included in the
software so you can use a standard scipy built.
As fitting model you may enter anything that python understands, e.g.:
or you can use predefined tokens, e.g.
for a constant background, a gaussian and two lorentian peak shapes.
