CDN-231: Projected Lensing Observable

CDN-231 converts the frozen CDN-229 lensing-parity masses into a projected excess-surface-density observable. On the held-out SPARC half, after a 0.65 kpc projection cut, 1368 of 1514 points have positive projected baryonic and dynamic DeltaSigma. The median held-out projected boost is DeltaSigma_dyn / DeltaSigma_bar = 1.606, with median response share 0.377. This is a forward observable, not an observed galaxy-galaxy lensing pass.

Abstract

CDN-231 converts the frozen CDN-229 lensing-parity masses into a projected excess-surface-density observable. On the held-out SPARC half, after a 0.65 kpc projection cut, 1368 of 1514 points have positive projected baryonic and dynamic DeltaSigma. The median held-out projected boost is DeltaSigma_dyn / DeltaSigma_bar = 1.606, with median response share 0.377. This is a forward observable, not an observed galaxy-galaxy lensing pass.
