Mass fraction of the various XMP galaxy constituents. Top: the color code parametrizes the morphology as follows: red = symmetric, black = cometary, blue = two-knot, green = multi-knot and grey = no morphological information. The symbol code is □= M_DM, •= M_H   i, △  = M_He and ×  = M_⋆. The magenta and cyan line are, respectively, the one-to-one and 0.1 × Mass relation. Middle: the distribution of the mass fractions relative to the dynamical or H i mass. The color code is blue = , red = and green = . Bottom: the distribution of the dark matter and H i mass fractions relative to the dynamical mass, in percentage. The color code is blue = and red = . The magenta and cyan dashed lines are, respectively, the range for dark matter mass fractions in spiral and elliptical galaxies.
