From: Attosecond and nano-Coulomb electron bunches via the Zero Vector Potential mechanism

A log plot of the errors associated with the data of Fig. 2, when compared to the model. The orange triangles represent a failure of the model to predict the electron bunch mean energy. The best fit to the model is for the range \(10 \le a_0 \le 300\) and \(S \ge 1\).
