Clustering strength, as a function of redshift for all galaxies with errors based on a bootstrap estimate. The populations are split by mass, with triangles showing the 10^8.6 < M [h^-1 M_⊙] ≤ 10^9.6 samples, squares 10^9.6 < M [h^-1 M_⊙] ≤ 10^10.6, ×’s 10^10.6 < M [h^-1 M_⊙] ≤ 10¹¹ and circles M [h^-1 M_⊙] > 10¹¹. The curves give the results of the galform model for the observed mass ranges, as indicated in the legend. Results from Foucaud et al. (2010, grey asterisks and crosses connected by dashed lines) and Wake et al. (2011, grey stars connected by dashed lines) are also plotted.
