MetadataThis section provides information about 'RDS9999371'.

DefinitionA <TRISTIMULUS VALUES> is a <Property> that is a measure of the amounts of the three reference colour stimuli, in a given trichromatic system, that are required to match the colour of the stimulus considered. For a given colour stimulus described by the colour stimulus function phi_lambda(lambda) of a radiometric quantity X =k.integral[0, infinity](phi_lambda(lambda).x~(lambda)d.lambda) Y = =k.integral[0, infinity](phi_lambda(lambda).y~(lambda)d.lambda) Z = =k.integral[0, infinity](phi_lambda(lambda).z~(lambda)d.lambda) where x~, y~, z~ are the CIE colour matching functions and analogous expressions are for X_10, Y_10, Z_10
