Probability Pq of being a high-redshift quasar for simulated sources with an observed magnitude Yobs = 21.5 ± 0.14 (left panel) and Yobs = 22.0 ± 0.22 (right panel). This probability reaches from white (Pq = 0) to black (Pq = 1). The coloured points represent brown dwarf colours ranging from blue (L0) to red (T9). The black curve is the mean quasar spectrum derived by Pâris et al. (2011), for which we included IGM absorption.
