Notes. Parameters values for the 2D double β model fitting the exposure corrected image. The upper values are the one for the first component and the lower ones are for the second component. The first column reports the value of δ, the second column reports the core radius in [kpc] units, and the third column reports the amplitude of the model in [10⁻⁷ photons cm⁻² pixel⁻² s⁻¹] units. The forth and fifth columns report the values for ellipticity and angle of inclination, and the last column reports the reduced χ² value (it results relatively small due to the image being scaled by the exposure map and the number of degrees of freedom being high). All the errors reported are determined with a 1σ confidence level.
