Linear galaxy bias of luminous blue galaxies in VIPERS parent mocks. Top panel: points with error bars show the mean measurement and the related 1σ error of the linear galaxy bias for the luminous blue galaxies in the 153 parent mocks, together with their best-fit with a constant value over r = [5, 50] h⁻¹ Mpc (blue solid line). The red dashed line corresponds instead to the value yielded by MCMC using the Scoccimarro model, over the same rage of fitting scales. Bottom panel: the ratio of the measurements and the red dashed line in the top panel.
