(a) Cartoon structure of the floating bilayer example considered in this work. The membrane is supported by a grafted phospholipid coating and is separated from the substrate by a water cushion. (b) Direct splicing of MD profiles calculated separately for the lower layers and the bilayer can introduce discontinuities at the splicing point, as indicated by the arrow. (c) Squared gradient of the SLD profile shown in (b), which illustrates that under these conditions the discontinuity becomes a dominant feature introducing artefacts into any subsequent reflectivity calculation. |
