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.

120-123 I4 --- ref2 *? Page or Year for source of the elements
124-139 A16 --- name Name or preliminary designation of planet
141-158 A18 --- aut Author of the elements
159-164 I6 -- date *six-figure code of the date: YYMMDD
--------------------------------------------------------------------------------
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
