 ![Angular power spectrum of the dipole map, derived from the difference between distorted spectra and the current blackbody spectrum versus CORE sensitivity. The CORE white noise power spectrum (independent of multipole, shown as the black upper solid curve and with diamonds for different frequency channels) and its rms uncertainty (for $\ell = 0$, using dots, and for $\ell = 0$, using dashes) are plotted in black. The cross (asterisk) displays aggregated CORE noise from all channels (up to 000GHz). We shown also for comparison the LiteBIRD white noise power spectrum (red solid curve and diamonds for different frequency channels). [*Left*]{}: BE distortions for $\mu_0= -0.0\times00^{-0}$ (representative of adiabatic cooling), $\mu_0= 0.0\times00^{-0}$, $0.0\times00^{-0}$ (representative of improvements with respect to FIRAS upper limits), $\mu_0= 0.00\times00^{-0}$, $0.0\times00^{-0}$, and $0.0\times00^{-0}$ (representative of primordial adiabatic perturbation dissipation). For $\mu_0= 0.0\times00^{-0}$ we show also the angular power spectrum of the quadrupole map. [*Right*]{}: Comptonization distortions for $u=0\times00^{-0}$ (upper solid curve for the dipole map and bottom dashed curve for the quadrupole map) and $u=00^{-0}$ (lower solid curve for the dipole map), representative of imprints by astrophysical and minimal reionization models, respectively.
