3D cartoon of the molecular disk and outflow geometry in Mrk 231. The line of sight to the observer is perpendicular to the page. Red and blue colours represent the receding and approaching material for each component, respectively. The molecular disk consists of an inner disk, tilted by 58 deg on the line of sight, with a scale radius of 200 pc, plus and outer component with inclination 36 deg and scale radius 400 pc, with the line of nodes oriented in the east-west direction approximately. The molecular outflow is rendered by a wide-angle biconical-like component plus an isotropic one, represented here as a sphere for displaying purposes. For a detailed description of the cartoon see Sect. 5.
