Notes. All wavelengths are given in air. Columns 3 and 4 give the flux relative to F(Hβ) = 100 for each of the apertures, Col. 5 the dereddened relative flux of the combined spectrum, and Col. 6 the relative flux predicted by the Cloudy model. Line fluxes marked with colons are uncertain.

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.
