Elements of Minor Planets for 1986
    Batrakov Yu.V.
    <Izdatel'stvo Nauka, Leningrad (1985)>
================================================================================
ADC_Keywords: Ephemerides; Minor planets

Description:
  Osculating elements of minor planets numbered by November 1, 1984, are given.
  Perturbations by major planets were computed at the ITA of the USSR Academy
  of Sciences on a BESM-6 computer using programs by N.K. Sumzina and V.A. 
  Shor.

Note on code:
  A "1" in the i-th position of the code means that the perturbations from the 
        i-th major planet had been taken into consideration when determining 
        the elements.

Note on obs_yr1, obs_yr2:
  First and last year of the time interval covered by the observations used for
        improvement

Note on rms:
  Root-Mean-Square variation between observed and predicted positions.

Note on ref1:
  MP    = Minor Planet Circular
  EP    = Ephemerides of Minor Planets

Note on ref2:
  MP    => page
  EP    => year

Note on date:
  Six-figure code of the date when the set of elements have been computed and 
        written on tape at the ITA
