Notes. The errors in the emission line ratios are calculated through standard error propagation.

(a)

Observed fluxes normalized to F(Hα) = 100 and uncorrected for interstellar extinction.

(b)

Intrinsic surface brightness normalized to I(Hα) = 100 and corrected for interstellar extinction.

(c)

Numbers represent the S/N ratio of the quoted fluxes.

(d)

In units of 10-17 erg s-1 cm-2 arcsec-2.

(e)

The logarithmic extinction is derived by c = 1/0.348 × log ((Hα/Hβ)obs/2.85).

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.
