The CC-FIT2 program is a user-friendly tool for the i) fitting of AC susceptibilities using the (generalised) Debye model, ii) extraction of AC susceptibilities from waveform data, iii) fitting of DC magnetisation decays using (stretched) exponentials, iv) extraction of magnetic relaxation times with associated uncertainties and v) fitting the temperature dependence of these data accosting for uncertainties in the underlying relaxation times.

The program is written in Python and is freely available at the PyPi repository.
