Notes. Given the small angular separation of the companion, the false probability fraction (FPF) values were evaluated on the classically ADI reduced images following the prescription in Mawet et al. (2014), which accounts for small sample statistics. The final magnitudes are absolute values calculated taking into account the distance to the target and its uncertainties.
