PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
   EMR09420-6.SP3     GPS ephem. files for days 0-6, week #0942 in sp3 format 
   EMR09427.ERP       pole x,y and DUT1 solutions for week #0942
   EMR09427.SNX       station and EOP weekly combined solution in SINEX format
   EMR09427.SUM       name of this text summary file

REMARKS on EMR products:

1. ALGO receiver clock used as reference time. In the sp3 EPH file sat. clock
   correction value of 99999.999999 microseconds indicates that the direct clock 
   comparison with the reference clock is not available (e.g. ALGO not observing
   a satellite).
   ALGO clock error & drift were about 6975 nsec (50838) & 107 nsec/day
   w.r.t. GPS time.
   NRC1 clock error & drift were about -69 nsec (50841) & 3 nsec/day
   w.r.t. GPS time.

     (R) Satellite was removed from EMR SP3 file.
     (E) Satellite was excluded prior to processing data.
     (M) Satellite in maneuver.

3.  In order to mitigate the small number of fiducial stations available
    this week, we have constrained additional stations using ITRF96 
    coordinates transformed to ITRF94 (epoch 98.0).
