PRODUCTS GENERATED:
The following products are generated and uploaded into CDDIS @ NASA/GSFC
   EMR09040-6.SP3     GPS ephem. files for days 0-6, week #0904 in sp3 format 
   EMR09047.ERP       pole x,y and DUT1 solutions for week #0904
   EMR09047.SNX       station and EOP weekly combined solution in SINEX format
   EMR09047.SUM       name of this text summary file

REMARKS on EMR products:

	WARNING : Due to incomplete data set at ALGO, the following stations
		  were used as a reference station clock:
		  
		  NRC1 on 97May04 (50572) and 97May06 (50574).
		  FAIR on 97May05 (50573).

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).

2. NRC1 clock error & drift were about 51 nsec (50572) & -3 nsec/day
   w.r.t. GPS time.

   ALGO clock error & drift were about 124 nsec (50575) & 70 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.
