Notes. From left to right, the columns are as follows: Sequential ID for stars, RA, Dec, spectral type, and the reference study. The last two columns of the table present the Poisson distribution, P(n) = λne− λ/n !, of an observing one star, P(1), and one or more stars, 
, in the assigned Voronoi cell of each particular star on the density map of the observed isolated massive stars illustrated in Fig. 5. It is important to notice that the maximum value of the Poisson probability of observing one star, P(1) = λe− λ, is ~ 37%.
