Correlations between retrieved parameters. Comparison of results obtained in the center of NGC3309 (pink), in the center of NGC3311 (green), and in the outer regions and halos (blue). Numbers refer to the Spearman correlation coefficient with the same color-coding. The eccentricity of each ellipse is proportional to the calculated Spearman coefficient value. Strong correlations observed for NGC3309's center are generally not confirmed for the center of NGC3311.
