A corner plot of the inferred parameters of the 1-comp model. Here “t1,” “rstar,” “dist,” “scale,” and “logf” represent the temperature of the quiescent component, the star’s radius, the star’s distance, the scaling parameter, and additional noise present in the data, respectively. The model was constructed using the PHOENIX spectral grid and NIRISS data.
