obspy.signal.array_analysis.array_transff_freqslowness

array_transff_freqslowness(coords, slim, sstep, fmin, fmax, fstep, coordsys='lonlat')[source]

Returns array transfer function as a function of slowness difference and frequency.

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

  • slim – either a float to use symmetric limits for slowness differences or the tupel (sxmin, sxmax, symin, symax)

  • fmin (float) – minimum frequency in signal

  • fmax (float) – maximum frequency in signal

  • fstep (float) – frequency sample distance
