The difference spectrum ﹩{\rm{\Delta }}{C}_{{\ell }_{XY}}^{yy}﹩ computed from different LC combinations are shown. The difference spectrum should be consistent with zero in the absence of any bias, and we attribute the differences to the residual CIB bias arising due to tSZ × CIB. The error bars are computed using the square root of the diagonal of the covariance matrix of the difference spectrum in Equation (4). As is the case for ﹩{C}_{\ell }^{yy}﹩, the adjacent ℓ bins are highly correlated.
