obspy.signal.polarization.particle_motion_odr

particle_motion_odr(stream, noise_thres=0)

Computes the orientation of the particle motion vector based on an orthogonal regression algorithm.

Parameters

• stream (Stream) – ZNE sorted trace data

• noise_tres – variance of the noise sphere; data points are excluded when falling within the sphere of radius sqrt(noise_thres)

Returns

azimuth, incidence, error of azimuth, error of incidence
