Artificial stars and completeness levels. (a) Injected (red) and recovered (black) ASs in the m_F322W2 versus m_F150W2 − m_F322W2 CMD. The two green lines define the boundaries of the MS. (b)-(c) Completeness as a function of m_F150W2 and m_F322W2 magnitudes, respectively, with (red solid line) and without (green solid line) applying the PM selection, as well as without considering either the PM or RADXS selections (blue solid line). The dashed lines represent the completeness values in regions limited to the dark usable areas for detecting faint sources.
