If there is, what can it be used for (R-> n,k; k->n etc.) and what are your experiences with it in terms of ease-to-use? If there is not, what do you think are the reasons therefore?
All the older models of BIO RAD (Digilab Division) have this program. Presently BIO RAD (its spectroscopic division) is absorbed by VARIAN, thus you should search for KKT in spectrometers manufactured by VARIAN

Actually, what refFIT does is not a classical KKR analysis, instead Alexey uses a variational approach closer to dispersion analysis. In any way, I am not looking for some kind of software to do KKR myself, I am more generally interested to learn if KKR is still something obscure and does not work for the inexperienced user or if it is user-friendly and kind of mainstream nowadays.
