Notes. 

(a)

λ0 are the theoretical wavelength values from Kelly (1987).

(b)

λobs is the observed wavelength with the statistical 1σ error in parentheses.

(c)

In units 10-4 photons cm-2 s-1.

(d)

In units 10-13 erg cm-2 s-1.

(e)

Wavelength fixed at theoretical values.

(f)

Broad line.

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.
