Kernel density estimation of the parallax distribution of TGAS sources with 2 <ϖ< 3.5 mas (orange thick dashed line) and of the sources belonging to the density enhancements defined in the text (blue thick solid line). The fine lines represent the 5th and 95th percentiles and were computed with the bootstrapping procedure described in the text. The median value of the distribution is ϖ ~ 2.65 mas.
