super(EllipticalIsothermal, self).__init__(centre=centre, axis_ratio=axis_ratio, phi=phi,<EOL>einstein_radius=einstein_radius, slope=<NUM_LIT>)<EOL>
Represents an elliptical isothermal density distribution, which is equivalent to the elliptical power-law
density distribution for the value slope: float = 2.0

Parameters
----------
centre: (float, float)
    The (y,x) arc-second coordinates of the profile centre.
axis_ratio : float
    The elliptical mass profile's minor-to-major axis ratio (b/a).
phi : float
    Rotation angle of mass profile's ellipse counter-clockwise from positive x-axis.
einstein_radius : float
    The arc-second Einstein radius.
