obspy.signal.array_analysis.array_transff_wavenumber

array_transff_wavenumber(coords, klim, kstep, coordsys='lonlat')

Returns array transfer function as a function of wavenumber difference

Parameters:

• coords (numpy.ndarray) – coordinates of stations in longitude and latitude in degrees elevation in km, or x, y, z in km

• coordsys (str) – valid values: ‘lonlat’ and ‘xy’, choose which coordinates to use

• klim – either a float to use symmetric limits for wavenumber differences or the tuple (kxmin, kxmax, kymin, kymax)
