We are implementing lensing distortion from NFW halo to the image simulation in descwl-shear-sims (see LSSTDESC/descwl-shear-sims#198). It would be great to have the deflection angle from NFW halo to know how galaxy position changes under lensing. Also, it can be used to test high-order effect near the center of clusters.

Can you give us an equation for this?
