Table 5

Values of log 10(ξ) where Be-like Si xi to C-like Si ix reach the maximum ion concentration in the ionization balance adopting different ionizing SED.

SED AGN1 AGN2 PL

Si xi 1.90 2.03 1.90
Si x 1.72 1.94 1.71
Si ix 1.48 1.82 1.48

Notes. The three SEDs are adapted from Mehdipour et al. (2016). AGN1 and AGN2 refer to the SEDs of an archetypal Seyfert 1 galaxy NGC 5548 in a normal and obscured state. PL refers to a SED that follows the power law with Γ = 2.
