Notes. Reddening-corrected line fluxes, normalized to F(Hβ) = 100, for apertures defined by the HeII-emitting region (Fig. 3). The reddening coefficients, C(Hβ), and the value of the absorption correction, EWabs are listed in the last two rows for each HII region. The quoted uncertainties include measurement and reddening errors.
Emission-line fluxes from the inner, HeII-emitting part of the nebula (see Sect. 4.1.2 for details).
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.
