[Kristekova2009], Table 1. and 2.

Parameters:

st1 signal 1 of two signals to compare, type numpy.ndarray with shape (number of components, number of time samples) or (number of timesamples, ) for single component data st2 signal 2 of two signals to compare, type and shape as st1 dt time step between two samples in st1 and st2 fmin minimal frequency to be analyzed fmax maximal frequency to be analyzed nf number of frequencies (will be chosen with logarithmic spacing) w0 parameter for the wavelet, tradeoff between time and frequency resolution norm ‘global’ or ‘local’ normalization of the misfit st2_isref (bool) True if st2 is a reference signal, False if none is a reference

Returns:

Frequency-dependent Envelope Misfit, type numpy.ndarray with shape (nf,) for single component data and (number of components, nf) for multicomponent data
