Left: map of the integrated intensity of C¹⁸O integrated over velocities from 8 km s⁻¹ to 13 km s⁻¹. The velocity-coherent components of C¹⁸O emission are shown as the color contours. The magenta star indicates the position of the IRS 1 source that we consider in our analysis as the center of the hub of Mon R2. The effective beam size of 21.8^″ of the Nobeyama C¹⁸O observations is shown as the black circle in the lower left corner. The physical scale bar of 1 pc at the distance of 830 pc is shown in the lower right corner. Right: the position–position–velocity map of velocity-coherent structures, with colors the same as those in the left panel. This is available online as an interactive figure.
