Colour-magnitude diagrams for NGC 3532. Left and centre panels: all stars in the C11 catalogue; right panel: CMD in (V − K_s) and V with only the stars common to the 2MASS survey and the C11 sample. The grey stroke outlines the area defined as 0.1 mag bluer and 1 mag brighter than the hand-traced cluster sequence. In orange we show all stars that are both in the defined region, and are part of the dwarf sequence in Fig. 2. The seven confirmed white dwarfs in NGC 3532 are also marked (blue squares) in the first two panels.
