One halo term two halo term
WebA halo density profile is split into two parts, an inner (orbiting or 1-halo) profile and an outer profile (infalling plus 2-halo term). The outer profile can consist of the sum of a number of possible terms, such as the mean density, a power law, or a 2-halo term based on the matter-matter correlation function.
