Colour-magnitude diagrams of ω Cen using JWST filters. (a) m_F150W2 versus m_F150W2 − m_F322W2 CMD. (b) m_F322W2 versus m_F150W2 − m_F322W2 CMD. In both panels, black dots represent stars passing the quality selections while grey dots represent stars not passing the selections. The shaded light red and dark red regions highlight areas of the CMDs affected by saturation. The light red region corresponds to saturated photometry, while the dark red region represents severe saturation, where the photometry is saturated even in the frame zero.
