 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
     From GPS week 0982 - 1020:
       BOR1, GRAZ, KOSG, MATE, ONSA, POTS, REYK, WTZR, ZIMM, ZWEN, VILL, GRAS
   - For the realization of the ITRF97 reference frame the following sites
     are used from GPS week 1021 onwards:
       BOR1, GRAZ, KOSG, MATE, ONSA, POTS, REYK, WTZR, ZWEN, VILL, GRAS
       NYA1, THU1, TRO1. 
 - 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.

 -----------------------------------------------------------------------------
 
 REMARKS: - Site OBER 14208M001 from one AC was excluded from the combination 
            due to an antenna type error.
          - Starting with this week ITRF97 is used as reference frame.
          - Please note that the sites used to generate  the fixed coordinates 
            in ITRF97 are changed. Three IGS core sites NYA1, THU1 and TRO1
            were added. ZIMM is excluded due to a change in antenna and an
            resulting height offset versus ITRF97 coordinates.
