Brγ pure-line differential phases (left) and on-sky photocenter shifts (right) with respect to the continuum photocenter (at (0, 0)) as a function of velocity coded from blue to red. On the pure-line phases, the colored lines correspond to the observed total differential phases. On the photocenter plot, the light-yellow line and cones correspond to the position angle of the inner disk and its uncertainty, respectively. The dotted black circle represents the size of the star.
