Composite image of different protoplanetary disks at four different forbidden emission lines. First column shows the dust continuum emission at 1.3 mm from ALMA cycle 4 (Long et al. 2018, 2019). Other columns show the different forbidden emission lines from MUSE as labeled in the top left of the first row. Dashed yellow rectangles mark the area from where we gather the spectrum of the jet by summing over the spatial axes within the dashed yellow frame of the image.
