摘要：
We 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 modi. cation of the usual projected density estimator, with weightings that produce a spherical aperture rather than a cylindrical one.
