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) – 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
