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]_
