Notes.

^(a)

Observed continuum flux at 1470 Å (10⁻¹⁴ erg cm⁻² s⁻¹ Å).

^(b)

Fitted continuum flux extrapolated to 912 Å and corrected for extinction assuming E(B − V)=0.107 (10⁻¹⁴ erg cm⁻² s⁻¹ Å).

^(c)

Fraction of the continuum transmitted by the obscurer (Mehdipour et al. 2017).

^(d)

Extinction-corrected continuum flux at 1470 Å (10⁻¹⁴ erg cm⁻² s⁻¹ Å).

^(e)

Inferred ionizing continuum flux at 912 Å corrected for extinction and diminished by transmission through the obscurer (10⁻¹⁴ erg cm⁻² s⁻¹ Å).
