I/217               Orbital Elements of Minor Planets 1996  (Batrakov+ 1995)

Catalogue of Orbital Elements and Photometric parameters of 6160 Minor Planets numbered by 18 November, 1994 Batrakov Yu.V., Shor V.A. <Institute of Theoretical Astronomy, St. Petersburg, Russia (1995)>
ADC_Keywords: Minor planets Description: The catalogue contains osculating elements of all permanently numbered minor planets as of November 18, 1994. The elements are given with respect to the ecliptic plane and equinox J2000 for the standard epoch JD2450400.5 = 1996 November 13.0 ET. The elements of (719) Albert which is considered to be lost are given for the epoch when the planet was discovered. The catalogue data, in general, correspond to those published in "Ephemerides of Minor Planets for 1996", St.Petersburg, 1995. Along with these data the catalogue incorporates some connected information. File Summary:

Note (1): The elements are given with respect to the ecliptic plane and equinox J2000 for the standard epoch JD2450400.5 = 1996 November 13.0 ET. (see Description above) Note (2): When the column is blank, the default value of the slope parameter, G, is equal to 0.15, Note (3): code consisting of zeros and ones; 1 in i-th position of the code means that perturbations from the i-th major planet (counting from Mercury to Pluto) has been taken into account when determining the elements; 10-th to 12-th positions of the code are used for indication of perturbations from Ceres, Pallas, Vesta. Note (4): mean-root-square residual or maximum residual of observations with respect to set of elements fitted by least squares. In the last case 50 is added to the absolute value of the residual Note (5): code for the source of elements consisting of one or two letters and four or five digits; the letters MP and four digits or M and five digits stand for the Minor Planet Circular and the number of page; the letters EP and four digits stand for the Ephemerides of Minor Planets and the year.
