Adding keyword "sturm" solved the issue.
So adding an image seems redundant now...

I assume sturmian root solver (?) is needed for quadratic_spline only as this
one results in non-smooth transitions at the intermediate points. (as
cubic_spline did not need the sturmian solver)

Thanks (again... ;) ) Peter
