Fig. 2: [r] data at the left and right transition points.
Dashed lines in a, b mark the lengths exceeding which the [r] values for gx = 0.5, 1.1 begin to grow. By contrast, c, d show the monotonic decrease of [r] at gx = 0.6, 1 toward rPoi. All data are taken from Fig. 1 with Wz = 0. e, f plot the [r]-difference ratios near the two transition points to assess the sharpness of the discontinuity for the underlying transition.
