Abstract base class for an elliptical Sersic light profile, used for computing its effective radius and
        Sersic constant.

        Parameters
        ----------
        centre : (float, float)
            The (y,x) arc-second coordinates of the profile centre.
        axis_ratio : float
            Ratio of light profiles ellipse's minor and major axes (b/a)
        phi : float
            Rotational angle of profiles ellipse counter-clockwise from positive x-axis
        intensity : float
            Overall intensity normalisation in the light profiles (electrons per second)
        effective_radius : float
            The circular radius containing half the light of this model_mapper
        sersic_index : Int
            Controls the concentration of the of the profile (lower value -> less concentrated, \
            higher value -> more concentrated).
