Difference, Δz/(1 + z_spec), as a function of z_spec between the biased (top) or unbiased (bottom) photometric redshifts estimated with our matched multifilter (MMF) and the spectroscopic redshifts from sources in Table 1. The statistical parameters noted illustrate the systematic overestimates or underestimates, mean μ and median μ_1/2, and the degree of scatter, σ, of the photometric redshifts ( and ) found using the MMF and the Pearson et al. (2013) SED. Error bars in the top panel are calculated from using Eqs. (1) and 3) while error bars in the bottom panel are derived from simulations described in Sect. 4. The gray band depicts the 1σ region centered in the median μ_1/2 value for each distribution.
