X-ray polarisation in AGN circumnuclear media - Polarisation framework and 2D torus models

Table 1

Free parameters of the torus model, with the adopted range of parameter values.

Parameter	Minimum	Maximum	Step
log N_H	22.0	26.0	0.2
Γ	1.0	3.0	0.2
log E_cut	1.5	2.9	0.2
CF	0.05	0.95	0.1
cos i	0.0	1.0	0.1

Notes. The five parameters are the equatorial hydrogen column density (log N_H), the photon index (Γ), the exponential cut-off energy (log E_cut), the covering factor (CF = cos θ), and the inclination (cos i). N_H and E_cut are expressed in units of cm⁻² and keV, respectively.
