Figure 2
The NeXus/HDF5 files specify axes in the NeXus McStas coordinate system. The standard coordinate frame in NeXus is the McStas coordinate frame, in which the Z axis points in the direction of the incident beam, the X axis is orthogonal to the Z axis in the horizontal plane and pointing left as seen from the source, and the Y axis points upwards to form a right-handed axis system. The origin is in the sample.
