The average of log(B obs. /B theo. ). a a is fixed to 200 m when the B theo. values are calculated. In this condition, locality of heterogeneities is not taken into consideration. b a is chosen from 150, 200, 600, or 1000 m to minimize the average of log(B obs. /B theo. ) all over the observed earthquakes at each station
