The correct form of the equation which defines ηC (reported on p. 10, first column, line 2 of the printed version) is the following:
ηC=h(T0(n+1)s)−h(T01)h(T0(n+1))−h(T01)

Moreover, in the published paper, there are several mismatches between captions and figures for Figs. 2,3,4 and 7,8,9,10,11. The correct coupling between captions and figures is reported in the following.
