Deprojecting Densities from Angular Cross-Correlations
arXiv:astro-ph/0212084 · doi:10.1086/367851
Abstract
I present a model-independent spherically symmetric density estimator to be used in the cross-correlation of imaging catalogs with objects of known redshift. The estimator is a simple modification of the usual projected density estimator, with weightings that produce a spherical aperture rather than a cylindrical one.
