Permittivity parameters estimated from the three E0 galaxies in our sample (orange squares with error bars) compared with the permittivity parameters estimated by Cesare et al. (2020) from the DMS disk galaxies. The purple squares with error bars show the means of the permittivity parameters found for the individual DMS galaxies. The light blue shaded areas show the posterior distributions of the three permittivity parameters found with an approximate procedure from the entire DMS sample, with the green dots indicating their median values and the yellow, red, and black contours indicating the 1σ, 2σ, and 3σ levels, respectively.
