NCS data and fitting curves for the powder sample of melamine of mass M = 2.298 g (top panels) and mass M = 0.290 g (bottom panels). The data recorded at backscattering are shown in the left panels, and the data recorded at forward scattering in the right panels. Colour coding: the total (focused in the TOF domain) NCS data (black points and error bars), total fitted signals (solid red grey line), the fitted recoil peaks of hydrogen (solid green line and green shaded area), carbon (solid red line), nitrogen (solid blue line), and aluminium from the sample container (solid violet line).
