Our spatially resolved spectral line data support the derivation of a gravitational lens model from 37 independent velocity channel maps using a pixel-based algorithm, from which we infer a velocity-dependent magnification factor $\\mu \\approx 7-22$ with a luminosity-weighted mean $\\left<\\mu\\right>\\approx 13$.
