Distribution of the fitted parameters obtained from the F3 flare riblets at Δt = 3.4 min just before the GOES peak. This is the timestep with the highest number of pixels identified as riblets. The green bars show the distribution of fitting to a single Gaussian curve. The red bars represent the distribution of parameters obtained from the main emission component of the double-Gaussian fitted profiles. The black curve is the cumulative of the green and red bars.
