(a) Injected ASs for the two sequences (blue and red points) in the m_F150W2 versus m_F150W2 − m_F322W2 CMD. Recovered ASs are represented in black. (b) Same as panel (a), but the black points now represent the real stars. (c)–(d) Completeness as a function of the m_F150W2 and m_F322W2 magnitude, respectively. The completeness for each sequence is represented using the same colour scheme as in panel (a). Shaded light red and dark red areas qualitatively mark magnitude ranges where MS stars are mildly or severely saturated in at least one filter.
