Top panel: ratio of the thick and the thin disc masses. Second panel: ratio of the CMC and the thick disc masses. Arrows indicate the velocity of galaxies with no CMC with the same colour-coding as the other symbols Third panel: ratio of the hot component and the thin disc masses. Bottom panel: ratio of the hot component and the cold component masses. Filled black dots correspond to gas-rich galaxies, and grey circles correspond to gas-poor galaxies.
