Mean energy measurements: a difference between measured mean beam energy and target beam energy vs target beam energy.
Spread measurements: a measured mean beam spread vs measured mean beam energy for the given energy points. A line shows the best fit of these points to a linear function (as a result of chi-square minimization)
Mean energy deviations: a measured mean energy deviations (so-called mean_energy_sys_err) vs measured mean beam energy for the given energy points.
Impact of mean energy deviations: a part of the mean energy deviation in total uncertainty (as d/√(d2 + s2), where d is the mean energy deviation and s is the mean spread) for the given energy points.
