Mrk 421. Spectral index vs. normalization flux (left panel) and energy cutoff vs. normalization flux (right panel) for intrinsic spectra values reported in the literature. The black circles correspond to the results in this work, the green diamonds are the previous HAWC long-term spectra reported in Coutiño de Leon et al. (2019), the blue downward triangles are the results reported for short-term spectra (<1 month; Albert et al. 2007a; Aleksić et al. 2010; Acciari et al. 2011a), and the gray squares are the reported values from observations when the source presented a high-activity state (Aleksić et al. 2010; Acciari et al. 2011a).
