Photometric SEDs of some quasar candidates. In the left part of each panel, we model the observed photometric data points with four types of spectral templates. Fluxes with S/N > 3 are marked with red circles, while those with lower values are shown with a bit transparent color. The best-fit quasar template and its associated synthetic photometry are presented with blue lines and circles. Models based on the galaxy and star/brown dwarf spectra are shown with magenta and yellow lines, with an additional fitted model of low-z sources displayed in gray color. The goodness-of-fit of each model and the estimated redshift are also reported (see main text for a detailed definition). We further indicate the calculated redshift probability distribution function, P(z) for quasar and galaxy models. Finally, the right part of each panel shows the multiband images of the z ≳ 6 quasar candidate, each trimmed to 6″ size on a side.
