    814 Astrometric positions of the first eight Saturnian satellites 
    made from 1982 May 28 to 1988 Aug. 1 obtained
    from 138 photographic plates taken in 30 nights in the years 1982 to
    1988 are presented. All positions are compared with those calculated
    by the theory TASS1.7 (Vienne & Duriez, 1998). The observed minus
    calculated residuals give rise to standard deviations smaller than
    0.3".

Note (1): Satellite numbers used in the catalogue conform to the conventional
           IAU numbering system. 0 is used to denote the planet.
           1: Mimas; 2:Enceladus; 3: Tethys; 4: Dione; 5: Rhea; 6: Titan;
           7: Hyperion; 8: Iapetus; 9: Phoebe
Note (2): 0: observation absent
          1: observation present

Note (3): The format of these table is the same used in the catalogue
 of Strugnell and Taylor (1990A&AS...83..289S). The reference system is defined
 by the mean equator and equinox J2000.
