<doc>
raw data from a single crystal diffractometer, extends :ref:`NXxbase`
This is the application definition for raw data from
a single crystal diffractometer
measuring in normal beam mode. It extends :ref:`NXxbase`,
so the full definition is the content of
:ref:`NXxbase` plus the data defined here. All angles are
logged in order to support arbitrary scans in
reciprocal space.
