ERRATUM: 'PHYSICAL PROPERTIES, BARYON CONTENT, AND EVOLUTION OF THE Lyα FOREST: NEW INSIGHTS FROM HIGH-RESOLUTION OBSERVATIONS AT z approx< 0.4' (ApJ, 658, 680 [2007])

摘要

In our original paper, an error was introduced in the computation of the differential column density distribution function, f(N_(HI)) = m/(ΔN_(H) ,I∑ΔX) = C_H ,IN_(HI)~(-β), where the total redshift path (SAX = 2.404) was mistakenly omitted. The constant C_HI, (in Table 7) should therefore be corrected by -0.38 dex. We attach a revised version of Figure 14, where f(N_(HI)) is plotted against log N_(HI) (note that in the original figure, for the histogram representation, systems with σ_N/N ≤ 0.4 were considered; we correct this so that only systems with σ_b/b “≤ 0.4 and σ_N/N ≤ 0.4 are considered).
