obspy.taup.tau.TauPyModel.get_pierce_points_geo

TauPyModel.get_pierce_points_geo(source_depth_in_km, source_latitude_in_deg, source_longitude_in_deg, receiver_latitude_in_deg, receiver_longitude_in_deg, phase_list=('ttall',), resample=False, add_depth=[], ray_param_tol=1e-06)[source]

Return pierce points of every given phase with geographical info.

Note

Note that the conversion from source and receiver latitudes and longitudes to epicentral distances respects the model’s flattening parameter, so this calculation can be performed for a ellipsoidal or spherical planet. However, the actual traveltime and raypath calculations are performed on a spherical planet. Ellipticity corrections of e.g. [Dziewonski1976] are not made.

Parameters:

  • source_depth_in_km (float) – Source depth in km

  • source_latitude_in_deg (float) – Source latitude in degrees

  • source_longitude_in_deg (float) – Source longitue in degrees

  • receiver_latitude_in_deg (float) – Receiver latitude in degrees

  • receiver_longitude_in_deg (float) – Receiver longitude in degrees

  • phase_list (list[str]) – List of phases for which travel times should be calculated. If this is empty, all phases in arrivals object will be used.

  • resample (bool) – adds sample points to allow for easy cartesian interpolation. This is especially useful for phases like Pdiff.

  • add_depth (list[float]) – List of additional depths for which to get pierce points.

  • ray_param_tol (float) – Absolute tolerance in s used in estimation of ray parameter.

Returns:

List of Arrival objects, each of which has the time, corresponding phase name, ray parameter, takeoff angle, etc. as attributes.

Return type:

Arrivals
