BINoculars is a tool for data reduction and analysis of large sets of surface diffraction data that have been acquired with a 2D X-ray detector. The intensity of each pixel of a 2D-detector is projected onto a 3-dimensional grid in reciprocal lattice coordinates using a binning algorithm. This allows for fast acquisition and processing of high-resolution datasets and results in a significant reduction of the size of the dataset. The subsequent analysis then proceeds in reciprocal space. It has evolved from the specific needs of the ID03 beamline at the ESRF, but it has a modular design and can be easily adjusted and extended to work with data from other beamlines or from other measurement techniques.
BornAgain is a software package to simulate and fit small-angle scattering at grazing incidence. It supports analysis of both X-ray (GISAXS) and neutron (GISANS) data. Its name, BornAgain, indicates the central role of the distorted wave Born approximation in the physical description of the scattering process. The software provides a generic framework for modeling multilayer samples with smooth or rough interfaces and with various types of embedded nanoparticles.
ROD is a program that can be used to do a refinement of a surface structure using surface X-ray diffraction data. All main features one encounters on surfaces, like roughness, relaxations, reconstructions and multiple domains, are taken into account. The most essential part of ROD is the calculation of the structure factor of the surface. ROD is complemented by two utilities: ANA and AVE: ANA can be used to integrate scans and to convert these into structure factors, while AVE can sort and average data, determine agreement factors and produce a data file for the program ROD.
