“…For GRBs with two or more flares, the sum of these flare energies is considered as the flare energy E flare , which can be obtained by E flare = 4πD 2 L S F /(1 + z), where D L and S F are the luminosity distance and the fluence of X-ray flares, respectively. Meanwhile, the corresponding E γ,iso can be obtained from Li Y et al (2016), Ruffini et al (2018), , Tang et al (2019), Fana Dirirsa et al (2019, Minaev & Pozanenko (2020), Hao et al (2020), andDu et al (2021). The X-ray flare data, including the redshift z, the isotropic energy of prompt emission E γ,iso , and the total flare energy E flare , are listed in Table 2.…”
