Description
CMB observations from the Planck satellite have provided cosmic variance limited temperature measurement at large and intermediate scales. In the next couple of years, ground-based experiments such as SPT, ACT and Simons Observatory will make a high resolution measurement of CMB polarization, allowing the extraction of competitive cosmological informations from $C_\ell^{EE}$ and $C_\ell^{TE}$. Physics beyond the standard model, or unmodelled instrumental systematics could introduce some inconsistencies between $T$ and $E$ measurements with respect to the $\Lambda$CDM model. In this work we apply different methods to quantify a possible scale dependent T-E inconsistency in different CMB datasets : Planck, ACTPol and SPT3G.
