![]() Using mock galaxies, we demonstrate that combining a series of cross-correlation functions (CCFs) offers improvements over the 2PCF as follows: (1) The distribution of peculiar velocities in each split density is nearly Gaussian. ![]() We take a different perspective to split the galaxy density field according to the local density, and cross-correlate those densities with the entire galaxy field. the two-point correlation function (2PCF). 2013), and populate these haloes with mock galaxies using the Halo Occupation Distribution (HOD) model of Zheng, Coil
