Predicted UV LFs at high redshift. We show the LFs using the calibration (see Section 2.3) at z ∼ 5 from Bouwens et al. (2015a), with Planck 2015 cosmology (Planck Collaboration et al. 2015). Points show the binned UV and upper limits LFs from Oesch et al. (2013a, 2014), Finkelstein et al. (2015a), Bouwens et al. (2015a, 2015b). Shaded regions show the 1σ confidence range.
