Relative bias b∕b^* (see Eq. (12)) for the selected VUDS luminosity subsamples at z ~ 3 (orange circles) as a function of luminosity with L^* as a reference point. The results from this work are compared to similar studies at lower redshift ranges: at z ~ 0.1 from Zehavi et al. (2011) (filled black circles) and Norberg et al. (2002) (black crosses), and at z ~ 0.9 from Pollo et al. (2006) (green circles). The lines indicate the analytic fit of the 2dFGRS data from Norberg et al. (2002) (black solid line) and SDSS data from Tegmark et al. (2004) (black dashed line), as described in the text.
