Comparison among the posterior distributions of the apparent and true radius ratio and the effective temperatures of the host star and contaminant. Upper panels: posterior distributions of the true radius ratio (k_true) and the apparent radius ratio (k_app) for TOI-2081 (left) and TOI-4479 systems (right). Lower panels: posterior distributions of the effective temperature of the host star (T_{eff, h}) and the effective temperature of the contaminant (T_{eff, c}) for TOI-2081 (left) and TOI-4479 systems (right). The solid lines show the median of each distribution and the dashed lines show the lower and upper 1σ.
