Signal amplitudes in the vicinity of the putative exomoon around β Pic b suggested by Poon et al. (2024) as a function of moon mass and semi-major axis for RV studies on the left and astrometric searches on the right. The grey shaded region is the parameter space where a P24-moon is likely to reside if it is indeed real. The dashed lines indicate contours delineating the provided signal strengths.
