Figure 3

A color plot shows every pixel at 1° increments; each pixel is a safe zone with boundaries of ±10° anteversion and ± 10° inclination. For example, the red box located at 32° anteversion and 30° inclination reflects the dislocation ratio for the box-shaped zone with boundaries from 22° to 42° anteversion and 20° to 40° inclination. Since the color of the box is orange, the dislocation ratio for the zone is close to 1.5, with more dislocators than nondislocators. The light green and yellow pixels depict ratios close to 1.0 (an equal number of dislocators and nondislocators). The ‘Lewinnek safe zone’ is the pixel at 15° anteversion and 40° inclination; it is light green (ratio = 0.9). If it were a ‘safe zone’, it would be dark green in color (ratio = 0).
