(a) Distributions of the interface height fluctuations in real space (h(x)). (b) Discrete-time fast Fourier transforms of the interface height fluctuations in wave number (k)-space. (c) The average power spectrum of interface height fluctuations in k-space $\left(⟨{\left|h\left(k\right)\right|}^2⟩\right)$ colored in gray for CG and cyan for AA. Low wave number modes used in fitting the line tension (black for CG and blue for AA). (d) Variations in the inverse average power spectra of interface height fluctuations $\left({⟨{\left|h\left(k\right)\right|}^2⟩}^{-1}\right)$ as a function of k².
