obspy.taup.slowness_model.SlownessModel.split_layer

SlownessModel.split_layer(depth, is_p_wave)[source]

Split a slowness layer into two slowness layers.

The interpolation for splitting a layer is a Bullen p=Ar^B and so does not directly use information from the VelocityModel.

Parameters

  • depth (float) – The depth at which attempt a split, in km.

  • is_p_wave (bool) – Whether to split based on P (True) or S (False) wave.

Returns

Information about the split as (or if) it was performed, such that:

  • needed_split=True if a layer was actually split;

  • moved_sample=True if a layer was very close, and so moving the layer’s depth is better than making a very thin layer;

  • ray_param=..., the new ray parameter (in s/km), if the layer was split.

Return type
