Predicted overestimated value of planetary radius relative to the actual planet size as a function of (left) effective temperature and (right) atmospheric extension for the TESS and K bands for an edge-on orbit. Points denoted by black circles in the right plot are for model stellar atmospheres with T_eff ≤ 3700 K. The difference shown here is solely caused by assuming a quadratic limb-darkening law. For the left plot, the spread is due to differences in mass and gravity for a given effective temperature, and for the right-hand plot there are twenty chains caused by the combination of models having four values of gravity and five values of mass.
