68% and 95% CL constraints on the primordial perturbation power in general mixed ADI+CDI a); ADI+NDI b); and ADI+NVI c) models at two scales, k₁ = 0.002 Mpc^-1 (1) and k₂ = 0.100 Mpc^-1 (2), for Planck TT+lowP (grey regions highlighted by dotted contours), Planck TT+lowP+lensing (blue), and Planck TT, TE, EE+lowP (red). In the first panels, we also show contours for the pure adiabatic base ΛCDM model with the corresponding colours of solid lines.
