The largest mid-infrared atlas of active galactic nuclei at
  sub-arcsecond spatial scales
  We present the largest mid-infrared atlas of active galactic nuclei at
sub-arcsecond spatial scales containing 249 objects. It comprises all
ground-based HR MIR observations performed to date. This catalog includes a
large number of new observations. The photometry in multiple filters allows for
characterizing the properties of the dust emission for most objects. Because of
its size and characteristics, this sample is very well-suited for AGN
unification studies. In particular, we discuss the enlarged MIR--X-ray
correlation which extends over six orders of magnitude in luminosity and
potentially probes different physical mechanisms. Finally, tests for intrinsic
differences between the AGN types are presented and we discuss dependencies of
MIR--X-ray properties with respect to fundamental AGN parameters such as
accretion rate and the column density and covering factor of obscuring
material.
