Results of systematic ranging applied to 2008 TC₃ and 2014 AA.

Name	# Obs.	Time span	Sampling		Score		IP
		(min)	Grid/Spider	NEO	MBO	DO
2008 TC₃	4	43	log₁₀(ρ) - grid	100%	0	0	3.6%
2008 TC₃	7	99	Spider	100%	0	0	99.7%

2014 AA	7	28	Spider	100%	0	0	100.0%

Notes. The columns contain the name of the object, number of observations used, time span covered by the observations, characteristic of the sampling used to compute the MOV (grid or spider web), score of the object (NEA, MBA or Distant), and impact probability (IP).
