| D | e | 0.43 | 0.38 |  |
| ϑ | −59.1 | −63.3 |  |
|
| Γ | 0.10 | 0.12 |  |

Notes.
b is the mass strength in arcsec, e is the ellipticity and ϑ is its position angle in degrees (east of north), Γ is the external shear strength and Γϑ is the shear position angle in degrees (east of north). The density slope is given by γ, where γ = 2 corresponds to an isothermal profile. We report the best set of parameters recovered (Best) via the minimization with GRAVLENS and the average values (Mean), with the relative 95 percent confidence limit (CL), as assessed by the MCMC chains.
