MEASURAND : Fluence per monitor M1-count at 1 m distance from the target in vacuum in cm-2

NEUTRON ENERGY : 27.4 keV

The key comparison reference value, xR, and its standard uncertainty, uR, are obtained from the weighted mean of the participants' results.

xR = 1.752 cm-2 and uR = 0.022 cm-2
 

The degree of equivalence of each laboratory i with respect to the key comparison reference value is given by a pair of terms: Di = (xi - xR) and Ui, its expanded uncertainty (k = 2), Ui = 2(ui2 - uR2)1/2.

The degree of equivalence between two laboratories i and j is given by a pair of terms: Dij = Di - Dj = xi - xj and Uij, its expanded uncertainty (k = 2),
Uij = 2(ui2 + uj2)1/2.

The pair-wise degrees of equivalence are not explicitely given here, but can be found in Table A.3.1 to A.3.4 on page 26 and 27 of the Final Report.
