REMARKS on EMR products:
		
	WARNING: ALGO clock was reset on March 02 00:00 UTC by about -10596 ns.

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 10509 ns (50873), 96 ns (50875)
   & 81 ns/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.As of March 01, 1998 the NRCan solutions submitted to IGS are performed 
  using ITRF96 coordinates and velocities for the 47 IGS selected stations.
  A subset of the 47 stations is constrained to ITRF sigmas.

  The resulting discontinuities in NRCan products have been estimated 
  by processing Wk 947 both with ITRF94 coordinates and velocities for 
  the 13 fiducial stations as well as with ITRF96 coordinates and 
  velocities for the 47 selected stations.  The discontinuities are
  listed in Table 1.
