The set of modules/routines interpos are developed at the Swiss Plasma Center, Ecole Polytechnique Fédérale de Lausanne (SPC/EPFL), Switzerland. 

INTERPOS is a set of f90 routines which allow to interpolate data very easily and efficiently, to compute 1st or second derivative, to compute integral of a function or to extrapolate. It has also a very efficient matlab interface, python, idl as well
 
It can also smooth the data to the desired level with a"tension", using cubic splines with tension which minimizes the second derivatives.

Permission is obtained by sending a signed version of the code transfer agreement which can be found at http://spc.epfl.ch/interpos and in the file: ./Code_transfer_INTERPOS_generic.pdf

It states the following addiitonal conditions:

1.- The code does not change its name even if modified.

2.- Modifications of the code that are developed are made available to the SPC.

3.- Results produced with the original or the modified versions of INTERPOS should appropriately reference the original publications (to be coming so use at this stage):

4.- INTERPOS nor their progeny may be transferred or made available to other research groups without the written authorisation from the SPC.

INTERPOS is also installed and maintained at the ITER organization, therefore ITER-partners are granted the right to use INTERPOS, for non-commercial purposes, as certified by the file ./Code_transfer_INTERPOS_ITERandPartners.pdf
