Angular power spectra of the dark matter haloes in the lightcone at redshifts z = 0.5 and 1.5. The top panels show the clustering for haloes of mass 10¹³h⁻¹M_⊙ > M_h > 10¹²h⁻¹M_⊙, whereas the bottom panels display the corresponding results for 10¹²h⁻¹M_⊙ > M_h > 10¹¹ h⁻¹M_⊙. The lower panels show the ratios with respect to nonlinear theory, with dotted lines displaying the envelope for sample variance errors.
