Generates Mappings for Spectral Induced Polarization Simulation. Three parameters are required to be input: Chargeability (eta), Time constant (tau), and Frequency dependency (c). If there is no topography (indActive is None), model (m) can be either set to

m = np.r_[log(eta), log(tau), log(c)] or m = np.r_[eta, tau, c]

When indActive is not None, m is

m = np.r_[log(eta[indAcitve]), log(tau[indAcitve]), log(c[indAcitve])] or m = np.r_[eta[indAcitve], tau[indAcitve], c[indAcitve]] or
