Clustering-redshift (CC) measurements for the five tomographic bins and a broad bin with 0.1 <  z_B ≤ 1.2. The data points represent , that is, the redshift distribution after correction for the spectroscopic bias b_s(z), and the orange lines show the best-fit Gaussian-mixture-model (GMM) to these data. The blue lines show the same GMM but after correcting for the bias function ℬ(z) = (1 + z)^α with the best-fit α = 0.232 ± 0.441, showing a gentle skewing to lower redshift.
