With, X,Y,Z are the coordinates in the ITRF96, and Xs,Ys,Zs are the coordinates in the individual system.
.
T(t) = T(ts) + T . (t - ts) (2)
The quality analysis of the ITRF96 results is based more specifically on global residuals per solution (Table 2)
as well as per site. All residuals on a site-by-site basis resulting from the combination are available in the
file ITRF96.RESIDUALS.
