DESCRIPTION:Speakers: Andrew Nelson (ANSTO)\nrefnx [1] is a next generatio
 n reflectometry analysis package\, building on its predecessor\, Motofit. 
 It has undergone a large amount of collaborative development over the last
  five years\, introducing innovative features that greatly aid the nationa
 l and international neutron and X-ray reflectometry community:\n\n  - a Ba
 yesian statistics core with comprehensive uncertainty analyses and model s
 election ("how many layers can the data justify").\n  - quantitative intro
 duction of prior information into the modelling system (information known 
 from other sources)\n  - modular construction of structural models\, rangi
 ng from a basic Slab up to freeform SLD profiles and Lipid membrane leafle
 ts. These components are easily extensible.\n  - co-refinement of multiple
  contrast datasets.\n  - mixed Area models.\n  - Python based with analyse
 s performed in Jupyter notebooks or a Qt GUI.\n\nHere we give a brief intr
 oduction to how these aspects advance the reflectometry technique. In addi
 tion\, refnx is designed to enable reproducible research. We also discuss 
 what reproducible research means in the context of a neutron scattering st
 udy\, outlining how this is achieved with refnx\, and how these practices 
 could (should) be taken up by neutron scatterers in general.\n\n[1] Nelson
