Kernel density estimates (KDE) of the posterior probability distribution of compositional parameters of TOI-130 b inferred using BICEPS. The KDEs were calculated using a Gaussian Kernel with standard deviation of 0.2. Panel a: KDE of the layer mass fractions of TOI-130 b. Panel b: KDE of the mantle composition of TOI-130 b. White solid lines: indicate the contours of the 68%-HDR and 95%-HDR. White dashed lines: indicate the 68%-HDR and 95%-HDR of the posterior distribution calculated with the original model of D17.
