Notes.

(a)

The ratio of the observed J-band flux to the expected J-band flux, i.e., f = Jobs/Jexp.

(b)

Fits that have included the NIR channels. All fits have assumed a redshift of z = 3.08 and NH,X = 2.1 × 1022   cm-2 for simplicity, see Sects. 3.1 and 3.2.

(c)

Isotropic-equivalent energy calculated over the range of 0.1  keV to 104  keV (see, e.g., Elliott et al. 2012a).
