near-IR spectroscopic sample (see @vandokkum09b). Spectroscopic redshifts also exist for 125 LBGs at $z\sim3$ within the AEGIS field from @steidel03, for which we find $\sigma_{\rm z}/(1+z)=0.045$, with 10% $>5$ $\sigma$ outliers. From the formal EAZY errors listed in Table \[tab-1\], we find typical $\sigma_{\rm z}/(1+z)=0.04$, perfectly consistent with the scatter $\sigma_{\rm z}/(1+z)$ found for LBGs. We conclude that, in the regime of interest in this paper, the errors of the photometric redshifts are larger than at $z_{\rm spec}<1.5$, as they are dominated by random errors in the photometry.

The observed spectral energy distributions (SEDs) with best-fit EAZY templates over-plotted are shown in Figure \[fig-eazy1\], together with the EAZY redshift probability distributions. As shown in Figure \[fig-eazy1\], the medium-band filters $H_{1}$ and $H_{2}$ allow us to identify the redshifted Balmer/4000Å  breaks within the $H$ band, improving the accuracy of the photometric redshift estimates with respect to previous analysis with only broad-band photometry.

Rest-frame colors were measured using the best-fit EAZY templates, as described in @brammer09 and, in particular, in @whitaker10. Briefly, from the best-fit EAZY template, we computed the rest-frame $U-V$ colors following the method used by @wolf03 in the COMBO-17 survey. We used the @maizapellaniz06 filter definitions and used the
