Notes. Column (9) shows the reliability of the Voigt profile fitting, and column (10) indicates the metal transitions found at the same redshift of each BLA. The ionized hydrogen column densities in column (5) have been calculated using a constant α (turbulent-to-thermal Doppler contribution ratio) of 0.7. The uncertainties in column (5) reflect only the statistical uncertainties propagated from the line fitting. However, the inferred ionized hydrogen column densities are subject to systematic uncertainties due to the assumptions made to compute them. Columns (6), (7), and (8) show the range of variation in the determined log(NHII), log(T), and log fion, respectively, when using α values in the range [αlow - αhigh], with αlow = 0, and αhigh = 1.5, as detailed in Sect. 2.7.
