Figure 5
Variance of the noise reduction factor as a function of the number of shots in the case of the higher mean value (left panel) and of the lower mean value (right panel). In each plot the magenta curve is the theoretical fitting function \(y=a/x\), with \(a = 2.4 \pm 0.3\) in (a) and \(a = 3.4 \pm 0.8\) in (b), which is valid in the case of randomly distributed errors.
