Based on 4105 optical observations (of which 87 are rejected as outliers) from 2004-03-15.109 to 2013-05-07.150.

ADDITIONAL NOTE
The results contained in this impactor table are based on the Line Of Variations method generalised to the 7-dimensional space of the orbital elements and the Yarkovsky parameter. The Yarkovsky parameter has been estimated from the fit to the astrometry as (5.98 +/- 2.06) 10-15 au/d2, so that no a priori constraint based upon models and physical observations has been used.
The results are qualitatively compatible with the ones obtained at JPL, computed by using a priori information for the Yarkovsky effect computation and a Monte Carlo method, as described in the paper Farnocchia et al. (2013).
