Reducing the intrinsic scatter by computing the geometric mean NIV for N_seg distant or adjoined segments of N_b bins each. The data points indicate the results of individual simulations for adjoined segments. The lines depict the best fits to the simulations, using Eqs. (14) and (10), and the parameter values in Tables 2, and 3. The solid lines show the dependence of ∆_s,n on N_seg for adjoined segments, and the dotted lines for distant, randomly placed segments.
