Extended Data Fig. 2: Energy non-linearity.
From: Direct observation of coherent elastic antineutrino–nucleus scattering

Deviations from a purely linear energy scale measured with a pulse generator for the three Conus+ detectors. The trend of the data points are described by the black line. The vertical bars on the data points (coloured circles) represent the uncertainties at a 68% CL (1σ).
