Characteristics of the DES-Y1 BAO sample, as a function of redshift. Results are shown for a selection of the sample in bins according to DNF photo |$z$| (⁠|$z$|_photo) estimate in top of the table and BPZ in the bottom, both with MOF photometry. Here, |$\bar{z}=\lt z_{\mathrm{ true}}\gt$| is the mean true redshift, σ₆₈ and W₆₈ are the 68 per cent confidence widths of (⁠|$z$|_photo−|$z$|_true)/(1 + |$z$|_true) and |$z$|_true, respectively, all estimated from COSMOS–DES validation with SVC correction, as detailed in Section 4 and Fig. 7. f_star is the estimated stellar contamination fraction, see Section 6.
