Influence of the inclination on the velocity dispersion. We show different velocity dispersion distributions as a function of the galaxy inclination for different groups of redshift. We only show LTG and S0 galaxies for which we can compute the inclination using Meert et al. (2015). For the DPS, we show ΔV with red dots, σ_single of the single Gaussian approximation in blue (see Sect. 4.3.2) and in magenta (resp. cyan) the σ of the emission line component which is closer (resp. offset) to the stellar velocity in units of σ. We show the σ_gas for the NBCS with black dots. All data points represent the medians in the inclination intervals and the error bars the 16th to 84th percentiles.
