Description [src]
Computes the reduced shear assuming a lensed source at infinite redshift: $$ g(R) = \frac{\beta_s(zb)\gamma(R)}{1 - \beta_s(zb) \kappa(R)}, $$ where $\gamma(R)$ is the shear [nc_wl_surface_mass_density_shear()], $\kappa(R)$ is the convergence [nc_wl_surface_mass_density_convergence()], $z_b$ is the background-galaxy redshift and $$\beta_s = \frac{D_s}{D_l D_{ls}} \frac{D_\infty}{D_l D_{l\infty}}.$$ See [Applegate (2014)][XApplegate2014].
