Colour-magnitude diagram of the sample of Lupus stars identified in our membership analysis. The black solid line denotes the empirical isochrone of the Lupus association derived in this study (see Table A.3). The stars are colour-coded based on their membership probabilities which are scaled from zero to one. Triangles indicate the sources with RUWE ≥ 1.4 (see Sect. 4.1). The arrow indicates the extinction vector of A_V = 1 mag converted to the Gaia bands using the relative extinction values computed by Wang & Chen (2019).
