Star-to-brown dwarf ratio in the CNS5 for different distance limits.

r	# of stars	# of BDs	Total	Stars/BDs
6.5 pc	116	22	138	5.3 ± 1.4
8.0 pc	164	40	204	4.1 ± 0.8
10 pc	319	74	393	4.3 ± 0.6
15 pc	1066	231	1297	4.6 ± 0.4
20 pc	2590	413	3003	6.3 ± 0.3
25 pc	5230	701	5931	7.5 ± 0.3

Notes. The ratio increases significantly at distances larger than 15 pc, indicating that more brown dwarfs than stars are missing at larger distances.
