Results of different techniques are compared with each other, with and without masks in the regions of largest Galactic emissions. It is found that using a common analysis and masking as well as accounting for differences introduced by foreground models, the results from the two satellites are very similar. In particular, they yield values of $C(\Theta)$ very close to zero at $\Theta=90^\circ$ and $\Theta=30^\circ$, and significant negative correlation at $\Theta>160^\circ$. It is argued that these properties are consistent with symmetries predicted in holographic quantum models of inflation, but are unlikely to occur in the standard scenario.
