ALMA CO(1-0) data for IRAS F09111−1007W. Top left: moment-zero map. Overplotted are contours for outflow in the range [−510, −210] km s⁻¹ (blue) and [210, 510] km s⁻¹ (red), with contours at [0.35, 0.6, 1.1] mJy beam⁻¹. Top right: spectrum centered on the continuum nucleus. The spectrum is decomposed into three Gaussians, two for the host line profile and one for outflow (green). The black line includes all three Gaussian components. Outflow wings are detected on both sides of the line core. Center left: center positions and their errors, from UV fitting a Gaussian model to individual velocity channels. Center and bottom right: position-velocity diagrams. PA 0° is close to the bipolar outflow orientation, and orthogonal to the velocity gradient of the line core at PA ∼90°.
