No model has an apparent P‐wave shadow zone. However, three models have significantly shorter maximum distance for direct P waves with respect to direct S waves. For these models, the maximum direct P‐ and S‐wave ranges are indicated in parenthesis. References correspond to primary publications describing the generation method. The ranges of key parameters for the models are shown in Figure 2. Detail information for each model is shown in Figures 5 and 6 and in Ⓔ Figures S1–S12, available in the electronic supplement to this article.
