According to the results while this coupling was not satisfying

By using Rw = 50%, which is the average of the measured Rw for the PD173955 samples, Ta¯(k) is higher than 1 for the 7 Ks-PTFs of category II and is equal to 5.56, 5.06, 5.08, 7.58, 50.08, 2.03 and 6.39 respectively. Following these results, Ks-PTF of Wösten-1997 with Ta¯ = 50.08 is by far the most sensitive to BDm and consequently to Rw.
