(a) PNR data (points) and fits (lines) for a hBamA^(L7H9)BCDE/POPC membrane adsorbed to a DTSP-ANTA-Cu²⁺ functionalized gold surface, characterized in both spin-up (↑) and spin-down (↓) magnetic contrasts in D₂O (red data), Gold-matched water (gold data), PrMW (green data) and H₂O (blue data) solution isotopic contrasts. SLD profiles (top panels) and component volume fraction profiles (bottom panels) corresponding to fits shown in (a), describing (b), the complete interfacial structure and (c), the membrane-containing region. Shaded regions represent the 95% confidence intervals determined from MCMC resampling of fits to the experimental data.
