Notes. Δz = (zfit − zhost)×c, where zfit is the Lyα redshift of the best fit, zhost is the redshift derived from the X-shooter emission lines (Table 6), and c is the speed of light; log(NHI/cm−2) is the HI column density of the shell; Vexp is the shell expansion velocity; log(T/K) is the temperature of the gas; τd is the dust optical depth; FWHMi(Lyα) and EWi(Lyα) are the intrinsic FWHM and equivalent width of the Lyα line, respectively.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
