Evaluations of the χ² statistic of the correlation function (with respect to the null hypothesis) for different angular apertures. Only results for the foreground-cleaned SEVEM map are shown. There is evidence for kSZ signal in a wide range of apertures above the FWHM, with a local maximum close to 8 arcmin. This roughly corresponds to a radius of 0.8 h^-1 Mpc from the CG positions at the median redshift of the sample.
