Notes. The non-LTB parameters define the fiducial BEHOMO cosmology. The amplitude As of scalar perturbations and their spectral index ns are relative to the pivot scale kp = 0.05/Mpc. This ΛCDM cosmology gives σ8 = 0.79364 and t0 = 13.862 Gyr. Radiation has been neglected as neither the simulation nor the GR calculations include radiation.
