The mass profile for the moderately bright elliptical NGC 3377 is studiedthrough an spherical Jeans analysis, combined with a Bayesian approach. Theprior distributions are generated from dark matter simulations andobservational constraints. The observational data set consist of Gemini/GMOSlong-slit observations aligned with the major and minor axes of the galaxy, andare supplemented with data from the literature for the diffuse stellarcomponent, globular clusters and planetary nebulae. Although the galaxy isassumed to alternatively reside in central and satellite haloes, the comparisonwith literature results prefer the latter option. Several options of constantanisotropy are considered, as well as both NFW and Einasto mass profiles. Theanalysis points to an intermediate mass halo, presenting a virial mass around$(3.6\pm0.6)\times 10^{11}\,{\rm M_{\odot}}$.
