Slip-rate functions corresponding to the four values of risetime coefficient (cRT) considered in this study. Left panel shows functions in the time domain and right panel shows their Fourier amplitude spectra. The amplitudes of the functions are normalized to have unit area, and the time and period axes are normalized by the risetime value of t0, which corresponds to cRT = 2.2
