array_transff_wavenumber(coords, klim, kstep, coordsys='lonlat')[source]

Returns array transfer function as a function of wavenumber difference

  • 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)
