Period - eccentricity distribution of known BD companions. The new BD candidates from this paper are shown as solid diamonds. The circles represents the BDs from the combination of Table 1 in Ma & Ge (2014) and Table A.1 in Wilson et al. (2016). The size of all markers is proportional to the minimum mass (or mass represented by a black cross on top of the circles) of the corresponding object. The green color marks lower-mass BDs with m (or m sini) < 42.5 M_J, and the indigo color indicates high mass BDs with m (or m sini) > 42.5 M_J.
