Histograms of the luminosity-weighted velocity and velocity dispersion. Top row: MB. Middle row: NE halo. Bottom row: SW halo. Left column: Luminosity-weighted velocity. Right column: Luminosity-weighted velocity dispersion. The black color represents calculations made with the single-component fit, and the blue and red colors represent the principal and secondary double-component fit, respectively. Vertical solid thick lines represent the median of each distribution. The width of each cell on the x axis is 2 km s⁻¹
