Impact of different energy estimation methodologies on macroscopic flare scaling laws. (a) Scaling relationship between bolometric energy and GOES SXR 1–8 Å peak flux. (b) Flare frequency distribution (FFD) of the bolometric energy. (c) Relationship between bolometric energy and flare duration. The dashed lines represent the best power-law fits corresponding to the different datasets and energy estimation methodologies. r and γ denote the correlation coefficient of the fitting and derived power-law index, respectively.
