Informations.
         relative to: reference body is an occulting or eclipsing satellite:
                      J1 - Io       :  5,
                      J2 - Europa   : 18,
                      J3 - Ganymede :  2,
                      J4 - Callisto :  2
     reference frame: astrometric
     centre of frame: topocenter for mutual occultations or heliocenter for mutual eclipses
    epoch of equinox: J2000
          time scale: UTC
           reduction: from mutual occultations and eclipses
         coordinates: X, Y (topocentric for mutual occultations or heliocentric for mutual eclipses)
    diff. refraction: no information
            receptor: CCD, the field 4x4 arcmin2 with the resolution 0.26 arcsec per pixel
           telescope: 1.3-m F/8 Double Horseshoe telescope
           observers: no information
 data included in standard data file: no

Comments.
     1. The same observations, having been independently processed by another method, are also included in
        the portions jg0047 and jg0048 (see the lines where the observatory code is VBO).
     2. Standard R filter was used for all the events.
     3. For observations of J4 (Callisto) both DLC and DLCm intensity distribution models (see Vasundhara 
        et al. (2017), pp. 503–504) were used. Hence, eight lines of data giving relative coordinates of J4
        correspond to only four unique observations of this satellite.

Format.
  1. The type of the phenomenon (eclipse or occultation) including the satellite numbers. The type of
     phenomenon is coded as n_a o n_p or n_a e n_p for a mutual occultation or eclipse, respectively.
     Here $n_a$ is the number of the occulting or eclipsing satellite and $n_p$ is the number of the
     occulted or eclipsed satellite.
  2. The intensity distribution model that was used in the fit (DLC, DLCm, MLC).
     See explanations in Vasundhara et al. (2017), pp. 502–504.

 11. Y coordinate in arcseconds (topocentric for mutual occultations or heliocentric for mutual eclipses)
 12. "O-C" for X in arcseconds
 13. "O-C" for Y in arcseconds
 14. sigma of "O-C" for X in arcseconds
 15. sigma of "O-C" for Y in arcseconds
