dc.description.abstractrefnx [1] is a next generation reflectometry analysis package, building on its predecessor, Motofit. In this presentation we discuss its main design features: • Bayesian statistics core with comprehensive uncertainty analyses and model selection (”how many layers can the data justify”) [2]. • modular construction of structural models, ranging from a basic Slab up to freeform SLD profiles and Lipid membrane leaflets. These components are easily extensible. • Co-refinement of multiple contrast datasets. • Mixed Area models. • Python based with analyses performed in Jupyter notebooks or a Qt GUI. refnx is specifically designed to facilitate reproducible research. Here we also discuss what reproducible research means in the context of a neutron scattering study, outlining how this is achieved with refnx, and how these practices could (should) be taken up by neutron scatterers in general. © The Authorsen_AU
