Sensitivity analysis: the estimate of the total mass within 125 kpc (M125) for different GC samples. GCs within the rcut value are removed from the sample (for example, M125 at ﹩{r}_{\mathrm{cut}}=10﹩ corresponds to the mass estimate when GCs within 10 kpc are removed from the sample). Inner bars are 50% credible regions, and outer bars are 95% credible regions.
