VPD of the stellar association consulting the UCAC5 catalog. Panel a: maximum likelihood method assigns the Gaussian distribution bivariate elliptic to the 186 field stars. Points outside ellipse represent the rest of the region’s stars in the first analysis. Panel b: a zoom image of the square indicated in panel a. Open circles around the dots represent the 123 astrometric members that the maximum likelihood method assigns the Gaussian circular distribution bivariate. Panel c: open circles represent the 27 astrometric and spectrophotometric association Bo 7 members. All of them were obtained using the model proposed by Orellana et al. (2010).
