3) Combination Strategy:
========================
       The AC solutions are processed using the following procedure:
3-1) The AC solutions are checked/corrected for possible format problems,
     station names inconsistencies, etc...
3-2) The AC solutions are unconstrained according to the information provided
     in the SOLUTION/APRIORI Block.
3-3) The AC solutions are aligned (using a 7-parameters) and compared to the
     IGS00 stations at the current epoch.
     ftp://igscb.jpl.nasa.gov/igscb/station/coord/IGS01P37_RS54.SNX.Z
3-4) The AC are compared to IGS00, to each other, to the previous week
     solution and to the cumulative solution in order to identify and remove
     outliers.
3-5) The weekly AC solutions are combined and added to the cumulative
     combined solution. The cumulative combination is done to ensures 14
     parameters singularity.
     The weekly combined solution is aligned to the IGS00 of the current
     epoch using a 7-parameters transformation. The singular cumulative
     combined solution is aligned to the IGS00 of the reference epoch
     using a 14-parameters transformation and the 54 ITRF station positions
     and velocities. The IGS00 is a realization of ITRF2000.
     For more details, see:
     Blewitt, G., C. Boucher and J. Kouba, 1997, Procedure for ITRF continuous
       realization, the report of the IGS GB, presented to the IGS Governing 
       Board Meeting held in San Francisco, Dec. 11.

The combination software was developed at NRCan.

     4-1) Starting with GPS week 1143, the solutions are aligned to the
     IGS01P37_RS54.SNX realization of ITRF2000.

     is included in the erp files.
5) Results:

5-1)      AC (Variance Factor)^0.5 estimates:
==================================================
           The residuals used in the estimation of the Variance Factor
           are the differences between the cumulative combined solution
           and each AC weekly solution.
           SF = (Variance Factor)^0.5 = (Chi^2/dof)^0.5
           Final(SF) = Apriori(SF) * Aposteriori(SF)
