Peak intensities of 1 MeV electrons versus peak intensities of ∼100 keV electrons measured at STEREO A/SEPT & HET (top-left) and Solar Orbiter/EPT & HET (top-right) for four commonly observed events at both spacecraft. Legend boxes with corresponding colours have the values of slope and y-intercept for each fit on the scatter plots. The lower panel shows fits for the events observed by both spacecraft, with solid and dotted lines representing Solar Orbiter and STEREO A observations, respectively.
