Water maser positions relative to the continuum source. The left panel shows a wider field of view that encompasses all detected maser positions, while the right panel shows a zoomed-in region toward the continuum source (denoted in the left panel as the dashed box). The systemic velocity of HOPS 373 is ∼10 km s⁻¹, and the masers at blueshifted relative velocities are plotted as blue points, and those with redshifted relative velocities are plotted as red points. The nearly east–west outflow is plotted as the cyan and magenta lines to denote the blue- and redshifted sides of the outflow, respectively. The continuum source is plotted as the black cross at (0,0). The maser positions outside the central ±0﹩\mathop{.}\limits{^{\prime\prime} }﹩33 are from the D configuration at lower angular resolution; no masers were detected in the C-configuration observations.
