Our analysis addresses generic cross sections of the form $\\sigma\\propto v^n$, where v is the dark matter-baryon relative velocity, allowing for constraints on the cross section independent of specific particle physics models. We include high-$\\ell$ polarization data from Planck in our analysis, improving over previous constraints.
