    The key comparison reference value, xR, is based on the weighted mean of the participant results, with application of a cut-off uncertainty, as explained in Section 9.2 on page 93 of the Final Report. Its relative expanded uncertainty at a 95% level of confidence, UR, is determined as explained in the same Section of the Final Report.

    xR = 1.0029 [mW/(m2 nm)], UR = 2.1 %
     
    The degree of equivalence of laboratory i relative to the key comparison reference value is given by a pair of terms, both expressed in %: Di = (xi - xR)/xR and its expanded uncertainty Ui at a 95% level of confidence, Ui = (ULab i2 + UR2)1/2.
    The degree of equivalence between laboratories i and j is given by a pair of terms, both expressed in %: Dij = Di - Dj and its expanded uncertainty at a 95 % level of confidence, Uij ~ (ULab i2 + ULab j2 + UR2)1/2.
