Notes. The naming of the regions in the different hosts follows the one outlined in the line fitting plots, see Sect. 3. We also list the Hα EWs derived from the total line flux in each region and the flux ratio between narrow and broad component FB/FN. For GRBs 020903 and 050826 we add the two narrow components for the total Fnarrow, for GRBs 030329 and 060218 we add the two components in the wings for the total Fbroad. Vmax is defined in Sect. 4.4 as abs(Δv(narrow-broad) – 0.5 FWHMbroad) (see e.g. Veilleux et al. 2005; Arribas et al. 2014). For GRB 020903 and 050826 we use Δv(narrow-broad) between the bluest narrow and the broad component, for GRB 030329 we use the blue shifted additional component.
