Cumulative signal to noise ratio for the measurement of in the bin 0.9 <  z <  1.019 as a function of maximum multipole of analysis. Left, from top to bottom: Gaussian covariance only, Gaussian + “other NG”, Gaussian + SSC, Gaussian + SSC + 1h, total covariance. Right: zoom on the three lowest curves: Gaussian + SSC, Gaussian + SSC + 1h, total covariance, all normalised by the value of the signal to noise using the full multipole range and the total covariance.
