Comparison between (a) previously published diffraction data from a human serotonin receptor (Liu et al., 2013BB25) and (b) predicted diffraction of the same image region after successful optimization, with estimated background added. Diffraction is predicted using equation (19)[link] with the substitution [\Sigma_{\rm o}\rightarrow\Sigma_{\rm o}+\Sigma_{D}], corrected for the solid angle with equations (22)[link], (25)[link] to estimate the expected wavelength and summed up over all significantly excited Miller indices. Intensities are scaled according to the reference intensities deposited in the PDB (Protein Data Bank) under 4NC3 . The bandwidth of the X-ray beam is estimated to be about 0.1% [LCLS states 0.2% ΔE/E FWHM for the CXI beamline (LCLS, 2022BB23)].
