Centroid velocity maps from pixel-by-pixel Gaussian analysis showing pixels with intensity above 5σ for the redshifted (upper panel; integrated between 3.5 and 6 km s⁻¹) and blueshifted (lower panel; integrated between 0 and 3.5 km s⁻¹) features overlaid with continuum emission (blue contours) between 4σ and 300σ in 50σ intervals (σ=0.19 mJy beam⁻¹). Polygons representing the pixels included in the kinematic model of the streamers are shown in red (upper panel) and cyan (lower panel). The ALMA synthesised beam is shown in the lower left corner.
