Notes. Reddening E(B − V) is derived from the Balmer decrement (for low-resolution spectra), and electron density ne is derived from [S II]6717/6731 line ratios (for high-resolution spectra).
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.
