The measurement defines the relation between the requested output by a control channel and the physically achieved intensity. XML node for measurement is
The order of the measurements corresponds to their ascending physical values. Additional definition for additive color mixing: It is assumed that the physical value 0 exists and has zero output. Additional definition for subtractive color mixing: The flag is removed with physical value 0 and it does not affect the beam. Physical value 100 is maximally inserted and affects the beam.
Note 1: Some fixtures may vary in color response. These fixtures define multiple measurement points and corresponding interpolations.
