The ratio of the rms shot-noise contribution to the rms sample-variance contribution , of the covariance of the angular number densities N_i, as in Fig. 34. The fiducial curve that was shown in Fig. 34 is the solid line (mean WMAP7 cosmology), whereas the dashed, dot-dashed, and dotted lines correspond to the three cosmologies where either h, Ω_m, or σ₈, is changed to the value given in the second line of Table K.1.
