============
NXaberration

**Status**:

  base class, extends :ref:`NXobject`

**Description**:

  Quantified aberration coefficient in an aberration_model.

**Symbols**:

  No symbol table

**Groups cited**:
  none

**Structure**:

  .. _/NXaberration/magnitude-field:

  .. index:: magnitude (field)

  **magnitude**: (optional) :ref:`NX_NUMBER <NX_NUMBER>` {units=\ :ref:`NX_LENGTH <NX_LENGTH>`} 

    Value of the aberration coefficient.

  .. _/NXaberration/uncertainty-field:

  .. index:: uncertainty (field)

  **uncertainty**: (optional) :ref:`NX_NUMBER <NX_NUMBER>` {units=\ :ref:`NX_LENGTH <NX_LENGTH>`} 

    .. collapse:: Uncertainty of the value of the aberration coefficient ...

        Uncertainty of the value of the aberration coefficient
        according to uncertainty_model.

  .. _/NXaberration/uncertainty_model-field:

  .. index:: uncertainty_model (field)

  **uncertainty_model**: (optional) :ref:`NX_CHAR <NX_CHAR>` 

    .. collapse:: How was the uncertainty quantified e.g. via the 95% confidence interval ...

        How was the uncertainty quantified e.g. via the 95% confidence interval
        and using which algorithm or statistical model.

  .. _/NXaberration/delta_time-field:

  .. index:: delta_time (field)

  **delta_time**: (optional) :ref:`NX_NUMBER <NX_NUMBER>` {units=\ :ref:`NX_TIME <NX_TIME>`} 

    Time elapsed since the last measurement.

  .. _/NXaberration/angle-field:

  .. index:: angle (field)

  **angle**: (optional) :ref:`NX_NUMBER <NX_NUMBER>` {units=\ :ref:`NX_ANGLE <NX_ANGLE>`} 

    .. collapse:: For the CEOS definitions the C aberrations are radial-symmetric and have ...

        For the CEOS definitions the C aberrations are radial-symmetric and have
        no angle entry, while the A, B, D, S, or R aberrations are n-fold
        symmetric and have an angle entry.
        For the NION definitions the coordinate system differs to the one
        used in CEOS and instead two aberration coefficients a and b are used.

  .. _/NXaberration/name-field:

  .. index:: name (field)

  **name**: (optional) :ref:`NX_CHAR <NX_CHAR>` 

    Given name to this aberration.

  .. _/NXaberration/alias-field:

  .. index:: alias (field)

  **alias**: (optional) :ref:`NX_CHAR <NX_CHAR>` 

    Alias also used to name and refer to this specific type of aberration.
