total spectral radiance factor

βT(λ)

sum of the reflected spectral radiance factor, βR(λ), and the luminescent spectral radiance factor, βL(λ)
βT(λ) = βR(λ) + βL(λ)

Note 1 to entry: For fluorescence colorimetric applications, it is implicit that the quantity used in the colorimetric calculations is the total radiance factor, and it is common to omit the subscript T.

Note 2 to entry: The total spectral radiance factor has unit one.
