MEASURAND : Deviation from nominal angles 10", 5', 30', 5° and 30°
A key comparison reference value of EURAMET.L-K3.2009.1, xR, has beed determined for each block and position. The key comparison reference value is here calculated as the weighted mean of the two participants' results. Its standard uncertainty, uR, is calculated as the standard deviation of the weighted mean.
| For each angle block, the degree of equivalence of laboratory i with respect to the key comparison reference value is given by a pair of terms, both expressed in milliseconds: Di = (xi - xR) and its expanded uncertainty Ui = 2(ui2 - uR2)1/2. |
