versus (a) and (b) distributions for the complete (dashed elements) and sub (solid elements) spectral sample. The flux suggests a tight correlation at low values, but not for the most luminous GRBs. The solid line represents a least squares fit compatible with the correlation computed by statistical methods. (Figures after Lloyd et al. [173]; see Figure therein. @ AAS.
