 # Coordinate Estimates:   378    13    13    13

 WARNING: Due to the availability of only 4-5 fiducial stations, because of 
          the computer problems at JPL, this weeks results (orbit and eop) 
          were generated using the new set of (52) fiducial stations. 
          Because the coordinates of these stations are not given in the 
          ITRF94 we have used the ITRF96 coordinates. Because the 
          differences between the ITRF94 and ITRF96 reference frame are 
          much smaller than the problems caused by having only 4-5 fiducial 
          stations, this "solution" does not lead to any problems!
