Hertzsprung-Russell diagram showing the candidates with membership probabilities ≥90% (black dots). The blue crosses mark candidates located in the southern filaments (see Sect. 4.3). The isochrones (solid gray lines) and the lines of constant mass (dashed orange lines) are from the PARSEC series (Bressan et al. 2012; Pastorelli et al. 2020). A typical error bar is shown in the lower left corner. Objects located below the 30 Myr isochrone are considered contaminants. The right panel is the zoomed-in version of the left panel.
