    epoch of equinox: J2000
          time scale: TT
           reduction: from mutual eclipses
         coordinates: X, Y (heliocentric)
    diff. refraction: no information
            receptor: photometric
           telescope: See in the publication
           observers: See in the publication
 data included in standard data file: no

Comments.
     Data are deduced from the photometric observations
     of the mutual eclipses.
     For usual using of the apparent angular heliocentric 
     coordinates X, Y the data in the columns 1 to 6 are sufficient.
     Other data are needed for the application of the observational 
     results in the planetocentric coordinate system as explaned
     in the publication (see reference).
     The observatory codes K01, K02 are prelinary as these observatory
     are not mentionned in the MPC list. The coordinates of these
     oservatiries are following (MPC standard):
     K01  57.885  0.78881 +0.61463 Dushak-Erekdag
     K02  39.200  0.62068 +0.78407 Voronezh
         
Format.
