         1. The observations made in 1967-1969 are published 
            in Rose L. E. (1974) from Private communication (1970) 
            by Van Biesbroeck G.
         2. Time scales for the same observations published by
            Van Biesbroeck G. and Rose L. E. are different.

  1. Number of satellite (N sat)
  2. Year   of the moment of observation
  3. Month  of the moment of observation
  4. Day    of the moment of observation with decimals, 
            scale ET as given in Rose L. E. (1974)
  5. Day    of the moment of observation with decimals, 
            scale UT corrected for the light-time of the planet
            as given in Van Biesbroeck G. (1951) and Van Biesbroeck G. (1957),
            but 0.0 for the observations in 1967-1969.
