Table 5:

Ratio of cumulative signal-to-noise of the nulled set of power spectra over the original set of power spectra (SNR).
Nulling type	SNR	Step 3	Step 7	$z \in \left[ 0.5;1.3 \right]$
this work	0.179	$0.76\%$	$2.75\%$	$1.96\%$
standard	0.163	$0.59\%$	$2.32\%$	$1.45\%$

Notes. The results for the nulling method devised in this work and the standard nulling technique (Joachimi & Schneider 2009) are compared. The default SNR shown is computed for a step size in foreground redshift bin index i of 5 and in the redshift range $\left[ 0.4;1.4 \right]$ . In addition the moduli of the fractional deviation of the SNR from the default when using a step size of 3, i.e. every third bin i (third column), a step size of 7 (fourth column), and the default step size but a different redshift range $\left[ 0.5;1.3 \right]$ (fifth column) are given.
