Parameter values (fixed) for the ionising SED initially adopted from the broad band ionising continuum of NGC 7469 (Mehdipour et al. 2018, see Sect. 3.1 for details).
| Component | Parameter | Value | Reference |

| POW(a) | Norm (b) | 7.1 × 1051 | 1 |
| Γ | 2.1 | 2, 3, 4 | |
| COMT | Norm (c) | 5.7 × 1055 | 1 |
| Tdisk (eV) | 1.4 | ||
| Te (keV) | 0.14 | ||
| τ | 21 | ||
| REFL | Γ(d) | 2.1 | 2, 3, 4 |
| AFe | 2.45 (e) | 2, 3 | |
| Ec (keV) | 500 | 3 | |
| θinc | 60° | 3 | |
| Reflection scale | 0.5 | – | |
| σv (km s−1) | ∼3000 | 1 | |
Notes. To modify the SED to match with NGC 1068, some of the parameters were changed to observational results found in the literature, shown in the reference column. We assumed the ionising reflection was the same as the observed reflection, so we fitted only the normalisation of the REFL component.
We applied an upper and lower cut-off energy to the power-law: the lower cut-off energy (EL) is equal to the disk temperature (Tdisk) and the upper cut-off energy is EC = 500 keV (Bauer et al. 2015). The units for the normalisations are:
This value has been adjusted from Matt et al. (2004), Pounds & Vaughan (2006), who measured AFe = 2.4, to the abundance of Lodders et al. (2009).
