Notes. The total travel distance is Δ = Δ1 + Δ2. The exact distances of the arcs to the central point were computed by Δj = (ij − 1) Δx, where Δx = 0.46875° is the spatial resolution of the data. The quantities tinner and touter define the window that we used to model the travel-time fit (Gizon & Birch 2004).
