obspy.taup.slowness_layer.bullen_depth_for

bullen_depth_for(layer, ray_param, radius_of_planet, check=True)[source]

Finds the depth for a ray parameter within this layer.

Uses a Bullen interpolant, Ar^B. Special case for bot_p == 0 or bot_depth == radius_of_planet as these cause division by 0; use linear interpolation in this case.

The layer and ray_param parameters must be either 0-D, or both of the same shape.

Parameters
Returns

The depth (in km) for the specified ray parameter.

Return type
