Column description: ID: identification number; $z_{\rm phot}$: photometric redshift best-fit solution; $\chi ^2_{\nu }$: reduced $\chi^2$; $P_{\chi^2_{\nu}}$: probability relative to  $z_{\rm phot}$; AV: dust extinction parameter; $z_{{\rm inf}-90\%}$ and $z_{{\rm sup}-90\%}$: upper and lower bound for the $90\%$ confidence interval; $z_{\rm 2-phot}$: secondary solution for photometric redshift; $P_{\chi^2_{\nu};2}$: probability relative to  $z_{\rm 2-phot}$; log M: stellar mass in logarithmic scale, computed by using MA05 stellar population models.
We note that for galaxies with $z_{\rm phot}\sim 8{-}10$, the best fit redshifts are uncertain, and the range of equally probable solutions ( $z_{\rm inf}-z_{\rm sup}$) within the 90% of confidence is large. Also for some of these objects - marked by the footnotea - the Hyperzmass procedure did not find any physical solution for the best-fit SEDs by fixing the redshifts to these extremely high values.
a This value for the galaxy mass was found for the secondary solution of photometric redshift, z=3.753, because the Hyperzmass software did not find a plausible solution at z= 9.024.
