Extended Data Fig. 3: Compton form factor \(\pmb{\mathscr{H}}\) at −t = 0.26 GeV2 and at −t = 0.34 GeV2.

The imaginary (left) and real (right) parts of \({\mathscr{H}}\) are shown as a function of ξ. The red curve and the grey, red and blue bands are as in Extended Data Fig. 1. All uncertainties represent one standard deviation.
