Power spectra of ILC/CILC (full lines) and their noise residuals (dotted lines). Specifically, the orange curve is the power spectrum of the ILC-extracted Compton-y map. The lighter orange lines are the noise residuals. Specifically, they are the ILC residual CMB noise (r_CMB) and r_Atmo for the atmospheric noise. The blue lines represent the case with CILC where the CMB is deprojected. The solid, darker blue curve is the power spectrum of the CILC-extracted Compton-y map. The lighter blue curves are the noise residuals.
