         comparison of the individual solutions to the IGS Rapid solution.
         (first 6 hours of the prediction)

         The "igr" and "IGR" columns are zero since all centres are compared
         to the "igr" solution. Eclipsing satellites are flagged with an "E"
         beside the PRN number.
        "MEDI" stands for median of the centre's satellite RMS.

Table 3: Daily fit for each satellite and each centre resulting from the
         comparison of the individual solutions to the IGS Rapid solution.
         (24 hours of adjusted orbits)

         The "igr" and "IGR" columns are zero since all centres are compared
         to the "igr" solution. Eclipsing satellites are flagged with an "E"
         beside the PRN number.
         "MEDI" stands for median of the centre's satellite RMS.

         Remark: COU results for 06 UT are the prediction from the 00 UT
                 results, i.e. last 6 hours are predicted and
                 are therefore excluded from the comparison.
