On the Lx – L6 μm ratio as a diagnostic for Compton-thick AGN

Table 5

Numbers of low L_X/L_6 μm AGN (intrinsic L_X > 10⁴² erg s^-1) in the various samples, assuming the Fiore et al. (2009) relation for a 3% reflection efficiency.

	Total			Torus > 30%
	all	CT	non-CT	all	CT	non-CT

Local	22	10	12	14	6	8
CDFS	9	4	5	7(8)^†	4	3(4)^†

Notes.

^(†)

Source CDFS-407 has a low (30%) torus contribution in the 6 μm flux, but it would still be considered low L_X/L_6 μm taking into account this contribution.
