ETH‐2 0.269 0.256 −0.013
ETH‐3 0.705 0.691 −0.014
ETH‐4 0.524 0.507 −0.017

Note. The recalculated values were obtained by recalculation of all measurements with the Brand parameters, including the heated and equilibrated gases used to establish the reference frame and the values of the standards as published in 2014.
