      Application definition for data from two-dimensional area detectors that has been integrated azimuthally,
      with a certain radial binning in units of q or 2theta and with a binning around the azimuthal angle eta.

      An example application that creates these files is documented here: https://maxiv-science.github.io/azint_writer/

**Symbols**:

  The symbol(s) listed here will be used below to coordinate datasets with the same shape.

  **nImg**: Number of integrated images

  **nRad**: Number of radial bins

  **nRadEdge**: Number of radial bin edges (nRad+1)

  **nEta**: Number of azimuthal bins

  **nEtaEdge**: Number of azimuthal bin edges (nEta+1)

        .. index:: NXazint2d (applications)

        The ``NXsubentry`` or Multi-Method Data convention described here:
        https://manual.nexusformat.org/rules.html#table-nxsubentry
        should be used when different method (e.g. ``NXcanSAS`` or ``NXmonopd``), ``NXazint1d``
        or other ``NXazint2d`` data, integrated with different options, should
        be stored under the same ``NXentry``.

        In case of a single ``NXazint2d`` data processing the standard convention with
        the application definition directly under ``NXentry`` should be used.

          Declares which :ref:`NXdata` group 
          contains the data to be shown by default.
          It is needed to resolve ambiguity when more than one :ref:`NXdata` group exists. 
          The value is the name of the default :ref:`NXdata` group.

      .. collapse:: is a normalization correction applied or not. ...

          is a normalization correction applied or not.

          It indicates that integrated intensities and their errors were already divided by the appropriate normalization factors accounting
          for the effective number or weighted contribution of detector pixels to each integration bin.

    **monitor_applied**: (optional) :ref:`NX_BOOLEAN <NX_BOOLEAN>`

          is a monitor correction applied or not.

          The monitor correction accounts for external factors that are independent of the azimuthal integration process.
          Most commonly, this involves normalizing for fluctuations in the incident beam intensity or, where applicable, variations in exposure time.

            Values of the normalization correction.

            The normalization correction accounts for the effective number or weighted contribution of detector pixels to each integration bin.

            Note: An important aspect of the normalization strategy is how polarization and solid angle corrections are incorporated, which can vary
            depending on the specific application, software, and its configuration options (see, for example, PyFAI documentation).
            Additionally, the normalization strategy may include a relative or absolute calibration factor. Two common normalization approaches are:
            "Relative normalization" to the PONI (Point Of Normal Incidence) pixel, and "Absolute calibration", which yields the number of photons
            scattered by the sample in a given direction per unit solid angle. The type of the normalization strategy is not indicated on this level.
            It must be concluded from the software used or its parameters.

            The monitor correction is not included in the normalization correction and it is specified separately.
