Hi Marc,
the problem of linear passive FK processing that does not work correctly with version 3 and later, will be solved with 3.5 which we hope is actually cooming soon. We can hope that Geopsy will also be implemented with Raydec (since HVTFA "It looks for the very strong pure Rayleigh wave. On the contrary Raydec proposed by Manuel Hobiger uses the full signal length and stacks ") for all users who do not have Matlab ..?
Thanks and Best Regards
Luigi
