Comparison between MUSE IFS of image S0(d) (blue contours) and the ^3DBarolo model (red contours). The third row in the upper and bottom panels shows the residuals. Contour levels are set at 2σn, where the σ noise = 2 × 10⁻²⁰ erg s⁻¹ cm⁻² Å⁻¹ and n = 1, 2, 4, 8. The green cross shows the centroid position of S0(d). This plot shows the fitting result for the two lines of the [OII] emission doublet at (rest frame) λ = 3726 Å and 3729 Å in the upper and bottom panels, respectively.
