Notes. dPIE parameters inferred for the reference cored model of MACS 0416, with an rms equal to 0.63″. Coordinates are given in arcseconds relative to α = 64.0381417, δ = −24.0674722; e and θ are the ellipticity and position angle of the mass distribution. Error bars correspond to the 1σ confidence level. Parameters with ( * ) are stuck to a bound of the allowed prior. For an L* galaxy, we have σ = 237 ± 10 km s−1 and rs = 10 ± 2 kpc.
