Description:
These FITS images were generated with the IDL package MIRphot [Asmus2014]_ by extraction (and combination) of the sub-images from the chopped/nodded total images from COMICS, Michelle, T-ReCS and VISIR (see [Asmus2014]_ for details). The FITS images contain the central ~4 arcsec of each source centered on the (putative) nuclear position with North being up and East to the left. The WCS registration has been performed after extraction by using coordinates of the nucleus from other wavelengths (mostly 2MASS and NED). The uncertainty of these reference position is usually less than 1 arcsec. In addition, the imprecision of the assignment itself is ~1px ~ 0.1". The FITS images are flux calibrated (unit is mJy) using the Gaussian 2D fits to the corresponding STD observation (where available, otherwise using the median conversion factor for the used instrument/filter settings). Therefore, correction factors have to be applied in case other flux measurement methods are applied to the images. The flux values given in the FITS headers should be regarded as approximate values. In particular for the instruments, VISIR and COMICS, they are not necessarily exactly equal to the values provided in the photometry results table, because many flux measurements were performed during the process of combining individual subimages (all in MIRphot), instead of in the final combined image, provided here. The used total images are available upon request. Note, however, that these are just the products of the observatory-delivered pipelines with default parameters. ..

Description:
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 It includes in total 895 images, of which 60% are perviously unpublished.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.
