SRD ordering of extended similarity coefficients for a realistic fingerprint length, m = 1000, weighting was applied, number of objects compared was n = 13. X and left Y axes plot the scaled SRD values between 0 and 100. The Gaussian approximation of the discrete random distribution (~ 60 < SRD <  ~ 70) was omitted for clarity. The abbreviations can be found in Appendix 1
