Cross-section view of X-ray absorbing torus configurations assumed for the absroption-dominated (SW-A) and reflection-dominated (SW-R) models. The torus parameters of etorus given in Table 2 are illustrated. The inclination angle and half-opening angle are denoted as θ_i and θ_op; the labels of D, R1, and R2 represent direct light from the central X-ray source penetrating through the absorbing column in the line of sight, reflected light coming off from the part of the inner surface of the torus, which is hidden from direct view (“Reflection 1” as defined in Ikeda et al. 2009), and reflected light coming from the visible inner surface (“Reflection 2”), respectively. In SW-A, an observed spectrum is dominated by D and weaker R1, which has practically the same spectral shape as D. In SW-R, R2, which has a Compton-scattered low-energy tail, is the dominant component since D (and a minor R1 contribution) is strongly suppressed by the large optical depth in the line of sight.
