The Subarcsecond mid-infrared (MIR) atlas of local active galactic
nuclei (AGN) is a collection of all available N- and Q-band images
obtained at ground-based 8-meter class telescopes with public archives
(Gemini/Michelle, Gemini/T-ReCS, Subaru/COMICS, and VLT/VISIR). It
includes in total 895 images, of which 60% are perviously unpublished.
These correspond to 253 local AGN with a median redshift of 0.016. The
atlas contains the uniformly processed and calibrated images and
nuclear photometry obtained through Gauss and PSF fitting for all
objects and filters. This also includes measurements of the nuclear
extensions. In addition, the classifications of extended emission (if
present) and derived nuclear monochromatic 12 and 18 micron continuum
fluxes are available. Finally, flux ratios with the circumnuclear MIR
emission (measured by Spitzer) and total MIR emission of the galaxy
(measured by IRAS) are presented.
