Left: PDF of the prior on the internal luminosity distributions for WASP-48 b and EPIC-211418728 b under the linear- prior. The systems were chosen arbitrarily for illustrative purposes. Even if we initially set a uniform prior between 10^a and 10^b L_J, with a = 0 and b = 5, the actual prior distributions for each planet are not similar and have different a and b values. Notice the log scale for better visualization. Right: the heating efficiency prior distribution for EPIC-211418728 b. Assuming log-uniform prior distribution on L_int leads to biases toward smaller values on ϵ.
