The cumulative histogram p_c(ϵ,l) for the observation 06-02 computed for ϵ = 2.8. The length of the lines l is given in number of points of the lines (thus the total time of the line is given as t_l = lΔt). The estimate of the Rényi’s entropy K₂ = 0.0699 ± 0.0003 is obtained as the linear regression of the central part of the cumulative histogram (indicated by a solid red line, the dashed red lines indicate the used part of the histogram).
