               INTERNATIONAL EARTH ROTATION SERVICE
                 EARTH ORIENTATION PARAMETERS

                 Section 6 of the Bulletin B 102   
   
 6 - SUMMARY OF CONTRIBUTED EARTH ORIENTATION PARAMETERS SERIES
     This section gives the average precision of the individual series
 contributing to the combination and their average agreement with it. 
 Since June 30, GPS solutions are referred to ITRF94. In order to avoid
 discontinuities in the current combined solutions, all series have been
 referred back to ITRF93 system. Analyses of the next Bulletin B103 will
 take into account series in the ITRF94 system.
     For complete list of data, see Bulletin B in section 7.
     Units : 0.001" for x,y ,  0.0001s for UT1, 0.001" for dPsi, dEpsi.
