The AIA instrument on the Solar Dynamics Observatory obtains images of the sun in seven different extreme ultraviolet wavebands. Each filter produces images with distinctive appearance that is apparent to experienced observers. Subjective descriptions abound in the literature and in conference presentations, as do qualitative explanations of the physical reasons for these differences. We seek a quantitative description of the image properties, with the aim of understanding what the general image properties indicate about the temperature structure of the corona. Our preliminary results, obtained at multiple heliocentric angles above and below the limb, show that some channels consistently present a high or low intensity contrast which we attribute to the differing temperature, density and filling factor of the structures imaged. We also investigate the power spectra characteristic of each waveband. . Dimitri Kohler, Swiss Health Observatory (SHO). Stefan Otto, Federal Office of Public Health (FOPH) .
