Remarks

* - orbital type derived from osculating orbital elements

$ - diameter range derived from H and assumed albedo for C and S type - 0.04 and 0.20 respectively

# - 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.

R - as rotation quality code means Radar observations
