Luminous Efficiency Functions Spectral Power Distributions
==========================================================

Defines various luminous efficiency functions involved in spectral
computations.

The luminous efficiency data is in the form of a *dict* of
:class:`colour.colorimetry.spectrum.SpectralPowerDistribution` classes as
follows::

    {'name': SpectralPowerDistribution, ..., 'name': SpectralPowerDistribution}

The following luminous efficiency functions are available:

-   CIE 1924 Photopic Standard Observer [1]_
-   Judd Modified CIE 1951 Photopic Standard Observer [1]_
-   Judd-Vos Modified CIE 1978 Photopic Standard Observer [1]_
-   CIE 1964 Photopic 10 Degree Standard Observer [2]_
-   CIE 2008 2 Degree Physiologically Relevant LEF [3]_
-   CIE 2008 10 Degree Physiologically Relevant LEF [3]_
-   CIE 1951 Scotopic Standard Observer [1]_

Notes
-----
-   The luminous efficiency functions are provided at 1 nm steps.
-   The mesopic luminous efficiency function is calculated using the
    *CIE 1924 Photopic Standard Observer* and
    *CIE 1951 Scotopic Standard Observer* luminous efficiency functions with
    the :func:`colour.colorimetry.lefs.mesopic_luminous_efficiency_function`
    definition and the data from
    :attr:`colour.colorimetry.dataset.lefs.MESOPIC_X_DATA`
    attribute that defines weighting factors dependent on the photopic
    luminance :math:`L_p`. [3]_
