Caption: Figure 4.

Comparison of the calculations of the travel time delay integral from Equation (18) using the different codes considered. The inset shows a zoom-in around α = π/2, where the largest discrepancies between the codes are expected. The color code is the same as in Figure 3. Again, the agreement between the codes is superb.
