Notes. Photometric detection statistics for both companions. The aperture radius (Ap. rad.) is the radius used to extract the photometry of the sources. The confidence of the detection is denoted by the S/N ratio as described by Mawet et al. (2014) and FPF denotes the false positive fraction. The flux contrast with WISPIT 1 is corrected for neutral density filters where relevant.
