In fact all solutions contribute to the combined solution with the same weight. The rescaling factors of all centers are chosen such that they give the resulting EUREF solution realistic formal errors. - The ITRF93 coordinates (up to GPS week 0859) respectively the ITRF94 coordinates (since GPS week 0860) of the sites: BRUS, GRAZ, KOSG, MATE, METS, ONSA, WTZR, and ZIMM are used to align the solutions with the terrestrial reference frame. - The comparisons between each individual solution and the combined solution is done using a 7-parameter Helmert transformation. The Helmert parameters are determined using all sites of the individual solutions. - In the first Table unweighted rms values (for the coordinate components in the local system North-East-Up), derived from the Helmert residuals, are shown for each site. - In the second table an (unweighted) rms is computed for each Analysis Center. These values are derived from the Helmert residuals of all sites of a particular Analysis Center.
