Notes. Best-fit results of the elliptical deprojected radial spectral analysis of Abell 2009. In the first column the internal and outer radii of each elliptical annulus are reported (these radii correspond to the semi-major axes of the annuli). The second, third, forth, and fifth columns report the temperature, metallicity, normalization, and reduced χ² values of the fit, while the sixth, seventh, and eighth columns report the electron density, pressure, and entropy values.
