Zone where the best fitting model for CVn I in the chosen orbit is located. Each line represents the initial parameters needed to match the four observables used on this project: Final mass (blue), central surface brightness (cyan), effective radius (red), and velocity dispersion (green). The magenta crosses are the parameters of the Plummer spheres used to calculate the power laws of Sects. 3.1, 3.2, 3.3, and 3.4. The red circle is the final model and the black stars are the rejected models.
