Remarks

* - orbital type derived from osculating orbital elements

# - absolute magnitude H derived from astrometric observation via orbit determination - G value assumed to be 0.15

! - quality code according to Lagerkvist et al. (1989) in "Asteroids II" (Eds. R.P.Binzel et al.), Univ.Ariz.Press, Tucson, USA, pp. 1162-1179.

B - in rotation quality code means Binary asteroid

R - as rotation quality code means Radar observations
