Azimuthal deprojection of velocity and line width residuals obtained for the disc of MWC 480 as observed in 12CO and 13CO. The horizontal dashed and solid lines indicate the radial location of dust gaps and rings, respectively. The purple dotted line is the radial location of kink-like features observed in the datacube channels. The vertical lines denote the azimuthal location of the disc main axes as projected on the sky. The black lines overlaid in the line width residuals highlight the location of extended line width enhancements, likely associated to non-thermal motions. The green cross marks the location of the planet candidate reported in Sect. 3.2 based on 12CO line width enhancements. Cartesian versions of these maps can be found in Figs. 4 and B.7.
