ALMA CO(1-0) data for IRAS F05189−2524. Top left: moment-zero map. Overlaid contours are for the outflow in the velocity range [210, 510] km s−1 (red, 0.3 mJy beam−1) and the marginal emission at [−990, −270] km s−1 (blue, 0.2 mJy beam−1). Top right: spectrum in a r = 1″ aperture centered on the continuum nucleus. The spectrum is decomposed into three Gaussians, two for host and one for outflow (green). The black line includes all three Gaussian components. Outflow is clearly detected in the redshifted wing, and tentatively indicated for the blue wing. Center left: center positions and their errors, from UV fitting a Gaussian model to individual channels. Center and bottom right: position-velocity diagrams. PA +135° approximately follows the diffuse red outflow component towards the southeast or south, while PA +90° traces the velocity gradient of the line core.
