obspy.signal.polarization.flinn¶

flinn(stream, noise_thres=0)[source]¶

Computes the azimuth, incidence, rectilinearity and planarity after the eigenstructure decomposition method of [Flinn1965b].

Parameters:	stream (List of ZNE sorted numpy arrays) ZNE sorted trace data noise_tresh Variance of the noise sphere; data points are excluded when falling within the sphere of radius sqrt(noise_thres), default is set to 0.
Returns:	azimuth, incidence, rectilinearity, and planarity
