The resulting estimate for the Local Group mass, when shear information is included, is $4. 9 \times 10^{12} M_\odot$, with an error of $\pm0. 8 \times 10^{12} M_\odot$ from the 68% uncertainty in observables, and a 68% confidence interval of $^{+1. 3}_{-1. 4} \times 10^{12}M_\odot$ from the intrinsic scatter from the differences between the model and simulation masses.
