Color–magnitude diagrams of NGC 3532 in near-IR (left) and IR (right). The left panel also shows the isochrone corresponding to the age of 300 Myr, d = 484 pc, and extinction E(B − V) = 0.034. Cluster members shown in cyan, field sources shown in black, sources with X-ray counterparts in red–yellow color scale (with color indicating medium–soft hardness ratio (HR _ms ), and size proportional to the logarithm of the broadband flux (F _b )). Variable X-ray sources marked with asterisks. For the left panel, the AllWISE catalog, which crossmatches to 2MASS sources, is used for background sources. For the right panel, AllWISE+UnWISE+CatWISE2020 sources are used for background sources.
