2D histogram of intensity and velocity dispersion values for all fit components. The dashed line shows the lower limit for a chosen significance value of and a velocity dispersion value corresponding to the spectral resolution limit of the survey (0.21 km s⁻¹). The blue line shows the mean σ_v value per intensity bin. The number of bins in either direction is 400. The inset is a zoom-in of the most dense region of the distribution and uses a finer grid with 175 bins in either direction.
