Fig. 5


Values of the Fe Kα EW versus the equatorial column density of the torus () obtained by fitting the MIR spectra. Diamonds and circles represent values of obtained using the Galactic E(BV) /NH ratio and the average value of Maiolino et al. (2001b), respectively. The black (blue) filled diamonds (circles) are the corrected values (obtained using the model of Ikeda et al. 2009, see Eqs. (6) and (7)), while the empty red (cyan) diamonds (circles) are the uncorrected values. The values of EW were multiplied by an arbitrary constant factor for comparison. The data were rebinned to have six values per bin, and the uncertainties on the Fe Kα EW are calculated using the standard error of the mean. The dashed lines represent the expected trend for the set of parameters chosen for the renormalisation, calculated using the model of Ikeda et al. (2009). The expected trends were normalised to be compatible with the corrected data.
