Table 11 Mean angle between center-to-center lengths, standard deviation (S. D.), and % coefficient of variation (% C.V.) of four pores, taken from fingerprints obtained from the right thumb of four individuals on sticky side of adhesive tape (using method described in (iii)), recorded on ten consecutive days, show % C. V. to be within the normal acceptable level (with 5% confidence level in analytical work)

From: Reproducibility of fingerprint microfeatures
