Table 1: The non-dimensional times ( $\xi _k$ ), positions ( $\lambda _k$ ), thicknesses ( $\Delta r_k$ ), maximum densities ( $\rho _{\rm max}$ ) of the first ten caustics, the halo density itself ( $\rho _{\rm halo}$ ) at the positions of these caustics and other parameters used in expressions (3), (5)-(7). The present velocity dispersion is that for neutralinos which is about 0.03 cm s^-1. It is worth emphasizing that the thicknesses of the caustics do not depend on the halo parameters but only on the velocity dispersion of dark matter [see expression (6)]. It is instructive to compare the last two columns, which show that for a cluster-size halo with $r_{\rm vir}\sim 1$ Mpc, the caustic density can be many orders of magnitude higher than the halo density itself.
