Note:
1. Luminous intensity is measured with a light sensor and filter combination that approximates the CIE
eye-response curve.
2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
3. It use many parameters that correspond to the CIE 1931 2°. X,Y, and Z are CIE 1931 2°values of
Red, Green and Blue content of the measurement.
