\tablefoot{The results for the nulling method devised in this work and the standard nulling technique \citep{joachimi09} 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 $\bb{0.4;1.4}$. 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 $\bb{0.5;1.3}$ (fifth column) are given.}\vspace*{-0.25mm}
