For data like yours the attached script works quite well. As Robert suggested it
uses fmin_cobyla to fit a 4pt spline to the data subject to one constraint per
data point. Therefor it will be quite slow if applied to thousands of points.
Initially I tried to use it to determine the background of spectroscopic data
but this seems to be more difficult as the data is usually not as *smooth* as yours.
