Injection–recovery completeness ﹩{ \mathcal C }﹩ (fraction recovered/injected) for synthetic point sources injected into the raw ramps of PID 5594 and reduced through both pipelines, as a function of injected AB magnitude and apparent speed. Columns compare the reductions in group difference (top) against the standard ramp-fit products (middle) for F150W2 (left) and F322W2 (right). The difference in completeness (﹩{\rm{\Delta }}{ \mathcal C }﹩) between the group-difference and ramp-fit products is shown on the bottom. At injected speeds v higher than 5″ hr^–1, reductions in group difference reach fainter 50% completeness limits, with the gain increasing toward higher apparent rates. At v = 0, both reduction methods achieve the same sensitivity.
