(a) Flow diagram showing calculation of the emission location ( $[{\bf{r}}_{i,j,k}]$ ) and momentum directional unit vector ( $[{\bf{p}}_{i,j,k}]$ ) components. (b) A quiver plot showing the x–y component of each vector, $[{\bf{p}}_{i,j}]$ , for 1000 initialized 18.5 keV X-ray trajectories emitted from the plane z = z₀ − 3.0 mm. The minimum waists are $[\omega_{0,x}]$ = 0.015 µm and $[\omega_{0,y}]$ = 0.031 µm. No blurring factors have been included.
