Methodology : the most commonly used algorithm is the one developed by Silver and Chan
[Silver and Chan, 1991] together with the multiple-event method of Wolfe and Silver [Wolfe
and Silver, 1998]
A few other methods exist, as the cross-correlation (Bowman and Ando [Bowman and Ando,
1987] developed a method based on the maximal similarity in the pulse shapes of the two
rotated seismogram components) and the cross-convolution [Menke and Levin, 2003] one.
An other algorithm has been developed by Ivan Marian. Comparing results obtained by
performing two different methods (his, and the cross-convolution one) on data recorded at the
PSZ Hungarian station (GEOFON network) he found slight differences in the orientation of
the polarisation plane of the fast S-wave and in the delay times.
His codes are available through the ORFEUS system
