A beamline mirror or supermirror.
Symbols:
No symbol table
- Groups cited:
NXdata, NXgeometry, NXoff_geometry, NXshape, NXtransformations

Declares which child group contains a path leading to a NXdata group.
It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.

An array describing the thickness of each layer
depends_on: (optional) NX_CHAR
GEOMETRY: (optional) NXgeometry
DEPRECATED: Use the field depends_on and NXtransformations to position the mirror and NXoff_geometry to describe its shape instead
reflectivity: (optional) NXdata
Reflectivity as function of wavelength
shape: (optional) NXshape
DEPRECATED: Use NXoff_geometry instead
A NXshape group describing the shape of the mirror
figure_data: (optional) NXdata
Numerical description of the surface figure of the mirror.
OFF_GEOMETRY: (optional) NXoff_geometry
This group describes the shape of the beam line component
TRANSFORMATIONS: (optional) NXtransformations

This is the group recommended for holding the chain of translation and rotation operations necessary to position the component within the instrument. The dependency chain may however traverse similar groups in other component groups.
