Colour-colour plots of point-like XPS sources showing our separation between stars and no-stars using the hdbscan clustering algorithm (see Sect. 5.2). Left panel: g−z versus z−W1. Right panel: g−z versus J−K. Green triangles are sources classified as stars; blue circles are sources classified as no stars; grey asterisks show unclassified objects. Darker shades mean a higher density of sources.
