A comparison of observed arrival times from the Tomoves along-profile shot data (diamond symbols with a bar between the earliest and latest possible times for the first arrival) and the corresponding predicted first-arriving P times from the 3-D interpolated model (cross symbols). The horizontal axis shows the straight line distance in kilometres to each recording station from the first shot on each profile (i.e. shots A1, B1, C1, D1 and S1). Predicted times are only shown for shots and stations that lie within the bounds of the 3-D model.
