Inferred values of seven MOSFiT parameters for all 24 SNe in the MOSFiT sample. The parameters shown here are log M_ej, v_ej, log M_CSM, log ρ_CSM, with ρ_CSM in units of 10⁻¹² g/cm³, log R₀, with R₀ in units of 10¹⁴ cm, s, n, and t_exp for the CSI (circle) and RD+CSI (square) models. The blue circle in each plot highlights the Type Ibn OGLE-2014-SN-131. For the CSI sample, the lime and crimson circles correspond to the SNe with ρ_CSM above or below 10⁻¹⁴ g/cm³, respectively. Probability density functions (PDFs) produced with a Gaussian kernel density estimator are shown along the diagonal. Black and yellow curves correspond to the PDF of a specific parameter for the CSI and RD+CSI models, respectively. The subplot with red axes highlights the correlation between ρ_CSM and R₀, which is further explored in Fig. 8.
