Slope of the best-fit straight line to the middle section of the log-log field distribution plot, calculated as illustrated in Fig. 4. This plot shows each slope value plotted against the age of the AR from the start of its emergence (t = 0) at each time step and for each AR. Data for leading and following sunspots were separated. Second-order polynomials were least-squares fitted; they show the general trend.
