Top row: calibrated F444W and F210M contrast as a function of KLIP reduction parameters. Bottom row: S/N of synthetic companions after injection and recovery at a fixed contrast level, averaged across all position angles of injection, as a function of KLIP reduction parameters. The boxed region in all panels shows the subset of reduction geometries that achieve the best performance. These are considered for the final 5σ contrast curve calculation.
