Comparison of MLOCI reductions vs PCA and basic ADI reductions of NICI UY Pic data injected with simulated companions. The left panels in green show reductions for sky rotation equivalent to 0.35 × PSF FWHM (α = 0.35) of motion at 0.̋5 separation. The blue panels to the right show the ones for 1.25 × PSF FWHM of motion. The recovered companions can be seen at separations 0.̋5, 0.̋6, 0.̋7, and 0.̋8 with PA = 360, 270, 180, and 90°  respectively. The images have been normalized to the peak flux of the recovered companion at the top position (color scale is linear). The S/N improvements for MLOCI over PCA were 1.3 to 2.3 for α = 0.35 and 1.3 to 1.9 for α = 1.25. The S/Ns from PCA and basic ADI reductions were within 10% of each other.
