Halo catalogs from RayGalGroupSims run of a LCDM-WMAP7 model specified by the following set of cosmological parameters: Ω_m = 0.2573, Ω_b = 0.04356, h = 0.72, n_s = 0.963 and σ₈ = 0.801. The simulation covers a (2625 Mpc/h)³ volume with N_p = 4096³ particles. Halos were detected with the Spherical Overdensity (SO) algorithm with the overdensity threshold set to Δ=200ρ_c where ρ_c is the critical density. The catalogs have a conservative mass cut to M_200c ≥ 2·10¹³ M_sun/h corresponding to halos with more than 10⁴ particles.

Data files are in ascii format. The first row contains the total number of halos in the snapshot, the following rows contains the mass M_200c, M_500c and M_1000c of each SO(200_c) halo.

Fortran script for reading the files:
