Our sub-milliarcsecond precision measurements trace the proper motions of individual maser features in the plane of the sky. When combined with the direct line-of-sight radial velocity (v<SUB>lsr</SUB>), these measure the 3 D gas kinematics of the associated high-mass star formation region, allowing us to probe the dynamical processes to within 1000 AU of the core.STAMPAenConference paper10.1017/S1743921317010444https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/maser-emission-in-g-3398841259/FAA61D3984948B1E56B88BDDD044C1202018IAUS..336..334KFIS/05 - ASTRONOMIA E ASTROFISICA
