For large separations two-point correlators exhibit nearly scale invariance, while for short distances self-correlators need standard renormalization. We study the deformation of two-point correlators to smoothly match the self-correlators at coincidence. The corresponding angular power spectrum is evaluated in the Sachs-Wolfe regime of low multipoles. Scale invariance is maintained, but the amplitude of C(l)could change in a nontrivial way. %R 10.1103/PhysRevD.89.084037 %U http://arxiv.org/abs/arXiv:1401.6912 %U https://doi.org/10.1103/PhysRevD.89.084037 %P 084037-7pp
