Notes. Shown are the fit results for A, ηother, and β for various sample combinations. In addition we list the number of subsamples Nsample used for the joint fit and the reduced χ2 including p-value. The number of the degrees of freedom is given by 5 Nsample − 3. We have used flat priors A ∈ [0;20], ηother ∈ [−10;10], and β ∈ [−5;5], except for the case “MegaZ-LRG + L4 + L3”, where ηother ∈ [−20;20] was assumed instead.
