Notes.

^(a)

The flux of Hβ is 3.4 × 10⁻¹⁶ ergs cm⁻² s⁻¹.

^(b)

Corrected for heliocentric motions, but not the LMC redshift (∼ 270 km s⁻¹).

^(c)

The flux of Hβ is 8.1 × 10⁻¹⁶ ergs cm⁻² s⁻¹

^(d)

The flux of Hβ is 2.1 × 10⁻¹⁵ ergs cm⁻² s⁻¹.

^(e)

[O II] λ3727.5 was used for velocity estimate.

^(f)

λ3968.67 was used for velocity estimate.

^(g)

Deblending for [S II] was carried out assuming Gaussian line profiles.

^(h)

He Iλ5015 detected in the red wing of [O III] λ5007, but flux is uncertain.
