Line-of-sight velocity distributions of four bins. Open circles with error bars are the data. Overplotted are the model values for the best-fitting cored model (red) and NFW model (blue). Bins are located at (a) R = 297'', θ = 18°; (b) R = 550'', θ = 18°; (c) R = 1008'', θ = 45°; and (d) R = 2484'', θ = 45°. Quoted χ ² values are unreduced.
