CFHT photometric redshifts plotted against spectroscopic redshifts from SDSS. The left panel (star symbols) shows the z_ph for objects identified as stars in SDSS, the middle panel (filled circles) for normal galaxies, and the right panel (filled squares) for QSOs. A small inlay gives a zoomed version for z_spec ≈ 0.45 galaxies. The size of the symbols marking the photo-z estimate correspond to the quality parameter o (ODDS): big symbols for o > 0.9, medium-sized symbols for 0.8 < o < 0.9, and small symbols for 0.7 < o < 0.8. Error bars for the z_ph give the uncertainty interval defined by the BPZ Z_B_MIN and Z_B_MAX parameters. Objects inside a flagged region of one of the CFHT images (CANDMASK = 1) are shown in grey.
