a–c, The data points indicate the difference ΔE = E′ − E0 between the measured (E′) and theoretical (E0) energies of each detected line at the given X-ray energy. The best-fitting parabolic functions are given as solid curves. The error bars correspond to the 1σ confidence level. a, b and c show the results from sequence 100040020, 100040030–50 (combined) and 100040060, respectively.
