ASYURA

Overview

ASYURA
Advanced SYstem for User data Reduction and Analysis

ASYURA is a data-reduction, visualization, and analysis application developed for HODACA neutron-scattering data.

It provides tools for handling HODACA detector data, data binning and visualization, reciprocal-space conversion, background subtraction, vanadium correction, scan simulation, and analysis of both powder and single-crystal measurements.

ASYURA was originally developed by Hodaka Kikuchi at the Institute for Solid State Physics, The University of Tokyo.
