Abstract:
We use mid-infrared spectral decomposition to separate the 6µm
mid-infrared AGN continuum from the host emission in the ISO low
resolution spectra of 71 active galaxies and compare the results to
observed and intrinsic 2-10keV hard X-ray fluxes from the literature.
Description:
The 6µm flux refers to the AGN continuum exclusively and is
derived from ISO low resolution spectra. Most of the spectra are from
a rereduction of chopped ISOPHOT-S spectra of galactic nuclei in the
ISO archive (Spoon et al. 2004, in preparation). Hard X-ray data have
been taken from the references listed.

Note (1): Notes:
1: Uncertain type classification, see appendix.
2: `Elusive' AGN without NLR detection but listed as type 2 according
to the X-ray properties.
3: Stellar continuum may contribute a large part of the measured
6µm continuum
4: Assuming negligible absorption for Type 1 objects without NH
measurement.
5: Intrinsic flux cannot be recovered for Type 2 objects without NH
measurement or with lower limits to NH.
