Spirals in gas and dust for the IM Lup disk. From left to right: estimated perturbation in azimuthal velocity from the dust continuum using Eq. (9) and Eq. (14) (a), the estimated perturbation in radial velocity from the continuum using Eq. (14) (b), and the observed velocity residuals in the optically thick CO gas emission after subtracting a Keplerian model of the data (c).
