The top-left panel shows the difference in magnitude between the injected magnitudes and the raw uncorrected magnitudes (m_inj − m_raw) over the injected magnitude. The top-right panel shows the difference in magnitude between the injected magnitudes and the corrected magnitudes instead (m_inj − m_corr). The bottom row shows the number of standard deviations that the raw magnitudes ([m_inj − m_raw]/σ_raw; bottom-left panel) and corrected magnitudes ([m_inj − m_corr]/σ_corr; bottom-right panel) are removed from the injected magnitudes. The color in each panel represents the amount of background contamination (F_bkgd) that was present. The horizontal dashed lines in each panel indicate the median value of the entire sample.
