Same as previous figure for the thresholded Euler number densities. We still observe a transition towards the small scale. We note that here ξ_Euler(d) < − 1 showing that minima and maxima tend to be correlated at small distance (as confirmed in the next plot). Note: this measure is quite noisy as the Euler number density vanishes for low thresholded values and the threshold ρ_s > 0.5 is not shown.
