Velocity (coded by color) times flux (coded in color density) of MHO 3252 Y3 in H2 1–0 S(1) based on the OSIRIS low-resolution data that are displayed here on 50 mas pixels. The image was rotated by 71.°5 to show the jet axis approximately vertical. The velocity range displayed in the full RGB range is always 20 km−1 VLSR, but the velocity window has been shifted in the three different regions of the figure, separated by gray lines, so that the display parameters could be individually adjusted to the different intensities and velocity ranges of the emission features, so that the velocity structure of the jet is shown optimally. A continuum image of the star has been added in gray scale as a position reference. The highest velocities in the jet are near its center axis, while its envelope shows lower velocity owing to the entrainment of the wider low-velocity disk wind, the BLVC.
