m_F322W2 versus m_F150W2 − m_F322W2 CMD shown for three cases: without both PM and RADXS selections (a), with all photometric selections (b), and with both photometric and PM selections (c). The solid and dashed blue horizontal lines indicate the magnitudes at which completeness reaches 25% and 10%, respectively, across all CMDs, while the solid and dashed red lines represent the same for c_g. In (c), the two suspected BDs are highlighted as green triangles, with green error bars indicating their associated uncertainties.
