Square visibility of a star obtained using the analytical square root law (A, blue) and (orange) with a Hankel Transform (HT), with Radau quadrature for 12 µ values, plotted as a function of z = πθB/λ, where θ is in radian, and B and λ in meter (top). The difference between the square visibility of the star computed with these two methods (bottom).
