Notes. b is the critical radius of the lens galaxy, ΔxL and ΔyL are the positions of the lens (in right ascension and declination) with respect to the phase centre of the observations, ΔxS and ΔyS are the fitted positions of the source with respect to the lens, e is the ellipticity of the lens, θ is the position angle of the ellipticity, Γ is the external shear magnitude, and Γθ is the external shear position angle. All angles are in degrees, east of north.
