 Processing Strategy:
 --------------------

 - The combined weekly EUREF solution (EUR) is created after removing the 
   Analysis Center specific constraints.
 - Covariance rescaling factors are derived from the sampling rate used by
   each center. 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.
 - To align the EUREF weekly solutions with the terrestrial reference frame
   a selected set of "reference stations" is fixed to their ITRF coordinates.
   - For the realization of the ITRF94 reference frame the following sites
     were used (from GPS week 0860 to GPS week 0946):
       BRUS, GRAZ, KOSG, MATE, METS, ONSA, WTZR, ZIMM 
   - For the realization of the ITRF96 reference frame the following sites
     are used from GPS week 0947 - 0981:
       BOR1, GRAZ, KOSG, MATE, ONSA, POTS, REYK, WTZR, ZIMM, ZWEN, VILL
     and 
       GRAS 
     starting on week 0982.
 - 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.
