Notes. 

(a)

In units of 10-16 erg s-1 cm-2.

(b)

Fluxes are from the SDSS spectrum obtained with the round aperture of 3″ in diameter (Izotov & Thuan 2009).

(c)

Fluxes from the VLT/UVES spectrum obtained with a 1″ wide slit under non-photometric conditions (Izotov & Thuan 2009).

(d)

Fluxes from the VLT/Xshooter spectra within the apertures 1″ × 25 for the Hγ and Hβ lines and 09 × 25 for the Hα line (this paper).
