Comparison of centroid shifts and flux measurements with double-aperture photometry for detecting FPs. The results are produced for the case of variable transit parameters for the EBs. On the left, we show the efficiency for centroid shift measurements using the three types of masks mentioned in this work so far. On the right, we show the efficiency for both the secondary and extended masks. Both figures were obtained using 24 and 6 cameras for each mask. The Earth-like planet detection region is colored in light blue. The vertical dot-dashed red line corresponds to the P = 10.7 magnitude threshold. The pink colored region is the region where light curves will be produced on board for the P5 sample. The threshold of P = 11.7 is the vertical dashed green line.
