Saturated roughening and the front-runner.
(A) Interface widths (cm)for different front lengths L, data from September (month 4). Dashed line indicates power-law scaling. (B) Front-runner’s exceedance (Δmax), in cm, for different interface lengths L, data from month 4. Dashed line indicates power-law scaling. Note the log-log scales in both panels.
