Top: residual map (a.k.a CIB) auto- and cross-spectra measured at 217 and 353 GHz (circles). The dashed lines represent the measured power spectra corrected for the tSZ contamination (both tSZ and tSZ×CIB, see Eqs. (8) and (9), respectively). Bottom: absolute value of the ratio (continuous line) and (dot-dashed line, negative). The highest contamination is for the 217 × 217 power spectrum, where the total correction represents about 15% of the measured CIB power spectrum. For , the uncertainty is about 10%. On the contrary, is poorly constrained, as the model used to compute it is uncertain by a factor of two.
