Hα profiles in the region of the hinge clump. Each box represents an angular size of 1 arcsec, where the emission profile was integrated in this area. Asymmetric and double profiles can be identified at the north of the hinge clump ID26. We fit two Gaussians profiles on the observed emission, which are represented by blue and red profiles on each spaxel. North of the hinge clump, these components have a velocity difference of about 160 km s⁻¹.
