Effects of ƒ_R on disc geometry. Top left: changes in disc shape and geometry. Top-upper right: evolution of inclination with ƒ_R. Top-lower right: evolution of tilt with ƒ_R. Middle: evolution of the theoretical maximum gradient with ƒ_R. Bottom left: evolution of ƒ_R with ƒ_x. Bottom right: evolution of ƒ_R with ƒ_x. We note that this disc is centred on (δx, δy) = (0.67, 0.47) in ∆_ecl.
