Figure 5: Fractional deviation from the Gaussian mass function as a function of the peak height 𝜈 = 𝛿 c / 𝜎 . Different symbols refer to different redshifts as in Figure 4. The curves are the theoretical prediction (25) at 𝑧 = 0 with 𝑞 = 1 (solid) and 𝑞 = 0 . 7 5 (dotted). In the top panel, halos were identified using a spherical overdensity (SO) finder with a redshift-dependent overdensity threshold Δ v i r ( 𝑧 ) whereas, in the bottom panel, a Friends-of-Friends (FOF) finding algorithm with linking length 𝑏 = 0 . 2 was used.
