6.2.4. Yonetoku or *L* <sup>p</sup>–*E*<sup>p</sup> Correlation

This correlation reads *L*<sup>p</sup> ∝ *E* 2 p [65] and holds for both LGRBs and SGRBs [133]. Similarly to the *E*p–*E*iso correlation, the *L*p–*E*<sup>p</sup> correlation holds also within individual GRBs using time-resolved spectra. For details, see Ref. [130].
