Notes. dPIE parameters inferred for the mass model of AC 114, constrained using both SL and X-ray constraints, with an RMS equal to 0.43″. Error bars on all parameters quoted in this paper correspond to ±1σ confidence levels inferred from the MCMC optimisation. Coordinates are given in arcseconds relative to α = 344.701518, δ = –34.802364; e and θ are the ellipticity and position angle of the mass distribution. Each parameter is given as the median with the best fit value in parenthesis except the ones fixed a priori that are shown in brackets. For an L* galaxy, we have σ = 187 ± 5 km s−1 and rs = 11 ± 1.2″. The external shear component is equal to 0.11 ± 0.01, with an angle of 138.1 ± 0.8.
