Consistency between the combined LRG and SDSS Main samples. Shown is w_g +  for the red SDSS L4 (in black) and L3 (in red) samples. The solid curves correspond to the best-fit models to the combined L3 and L4 samples when varying A, η_other, and β. The corresponding best-fit models to the combined SDSS LRG and MegaZ-LRG samples are given by the dotted lines. The prior ranges A ∈ [0;20], η_other ∈ [ − 10;10], and β ∈ [−5;5] were employed in both cases. Note that the red points have been slightly offset horizontally for clarity, and that the error bars are correlated.
