Corner plot of the parameters inferred in the 2T model. Here T₀ denotes the temperature of the quiescent component and T_s the temperature of the cooler component, with s its covering fraction. Visit 3 is better modeled with a cooler component at ~2300K instead of ~2200K for visit 1 and 2. We assume that this is likely due to the coarse grid of temperatures of our model, as the likelihood distribution seems to have a single maximum (see Figure A.8).
