NFW halo lensing does not have deflection angle

Open mr-superonion opened this issue 2 years ago • 1 comments

We are implementing lensing distortion from NFW halo to the image simulation in descwl-shear-sims (see https://github.com/LSSTDESC/descwl-shear-sims/pull/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?
