       6 - SUMMARY OF CONTRIBUTED EARTH ORIENTATION PARAMETERS SERIES
     This section gives the average precision of the individual series contri-
 buting to the combination and their average agreement with it. The periods
 covered start at  the beginning of the first month in Section 1 and end with 
 the last available value in the individual series considered.
     The complete list of measurements is  available in the electronic-mailed
 version of Bulletin B in section 7.
    Units : 0.001" for x,y , 0.0001s for UT1, 0.001" for dPsi, dEpsi.
