Nonthermal electron fluxes F_e (upper row) and kinetic powers P_e (lower row) as a function of maximum GOES soft X-ray flux I_SXR (i.e., GOES class; here I_SXR = 10^-6 W m^-2 is a C1 flare, while I_SXR = 10^-4 W m^-2 represents an X1 flare) for the 18 flares analyzed. The left column shows the maximum values of F_e and P_e, the middle column the mean values (with the error bars showing the whole range from minimum to maximum), and the right column shows the total flux F_{e, tot} and kinetic energy E_e of the electrons in the different flares. Also shown are linear fits using the bisector method (dashed line) and the slope α.
