Colour-magnitude diagram in Gaia DR2 colour for NGC 3532 with cluster members highlighted. Radial velocity members from Fritzewski et al. (2019) are marked in orange and additional proper motion members in blue. The enormous field star population is shown in grey in the background. All data are dereddened with the average reddening value towards NGC 3532 (E_{GBP − GBP} = 0.046). Likely binaries are marked with squares. At the top, we indicate the different spectral types from Pecaut & Mamajek (2013) for orientation. The arrow indicates the Solar colour (Casagrande & VandenBerg 2018).
