Mass ratio distribution of all observed binaries to TESS planet candidates resolved in SOAR speckle imaging, including the individual distributions for large and small planet candidate hosting stars. The expected distribution of observed binaries based on the near-uniform mass ratio distribution of field stars (Raghavan et al. 2010) and the survey sensitivity is included. The observed mass distribution is consistent with uniform.
