Redshift evolution of the comoving clustering length for the two different parametrizations of clustering evolution. For the case of our model (Eq. (13)), shown as black and blue curves, the different evolution behaviours shown correspond to the indicated parameters (n,Mh). The specific values of these parameters have been chosen such as to resemble the ϵ = −1.2 and ϵ = 0 models of the traditional parametrization of Eq. (7), shown in red, which correspond to the constant in comoving coordinates clustering (for γ = 1.8) and to the stable clustering models (for details see the text).
