Table 1: Basic parameters of our sample of galaxies. Heliocentric redshifts z were taken from the NED, Seyfert types are according to Véron-Cetty & Véron (2000). The absorption corrected hard X-ray luminosities we compiled from the literature. Where multiple observations were available the average was taken. In these cases the reported uncertainties correspond to 1/2 of the peak-to-peak variabilities. In the case of PG 2130+099 only one measurement could be found. Here we assume a variability of a factor of 2. The last column contains the physical scales resolved by VISIR, computed for an angular resolution of $0 \hbox{$.\!\!^{\prime\prime}$ }35$ , which is a typical value for our observations (see Table 2).
Table 2: Basic observational parameters for all data used: Object name, observing date (in 2005), filter, flux and full width half maximum for standard star (STD) and science observations. As error estimates we use the standard deviation of all contributing beams (see section 2 for details). The FWHM are the average of all beams of one exposure. All science and corresponding STD exposures were obtained within a maximum airmass difference of 0.15.
