Fig. 7
Velocity dispersion map corrected for the instrumental LSF with HST contours overlaid in grey. Contours are logarithmic and smoothed using a 0.09′′ FWHM Gaussian. A threshold of 1.5 × 10-18 erg s-1 cm-2 arcsec-2 has been applied on the [O ii] surface brightness map smoothed using a 0.28′′ FWHM Gaussian, to mask regions with a too low signal-to-noise ratio.
