Plots of (a) the experimental gap sizes (crosses) as a function of photon energy between the third and 19th harmonics, plus the theoretical curves, as calculated with SRW (dashed lines); and (b) the theoretical photon flux after monochromatization by the DCM for all harmonics from the first to the 20th, also calculated using SRW. The diamond symbols are the experimentally determined fluxes, taking into account all correction factors associated with the beamline components and detector efficiency. Their colours indicate at which harmonic the flux was recorded.
