Comparison of VIPERS constraints on f_B and Ω_Mh with other galaxy surveys at low and high redshift. To test consistency with the cosmological model we have fixed the remaining cosmological parameters in the analysis of each survey. The expansion history is fixed to the fiducial model which restricts the allowed parameter space particularly at high redshift (compare with the VIPERS constraints in Fig. 7). Left panel: at low redshift we show the constraints from 2dFGRS at redshift z = 0.2 (Cole et al. 2005) and SDSS LRG at redshift z = 0.35 (Tegmark et al. 2004). Right panel: constraints from WiggleZ (Parkinson et al. 2012) are shown. In both panels the constraints from Planck are overplotted (Planck Collaboration XIII 2016).
