Amplitudes ATφ, errors σA, and significance levels (S/N) of the non-Gaussianity generated by the ISW effect for all component separation algorithms (C-R, NILC, SEVEM, and SMICA) and all the estimators (potential reconstruction, KSW, binned, and modal).

Notes. For the potential reconstruction case, an additional minimum variance (MV) map has been considered (see Planck Collaboration XVII 2014 for details).
