The thin and thick disc scale-heights (top and bottom panels, respectively) for gas-poor and gas-rich galaxies (grey circles and black dots, respectively). The black dashed line corresponds to a robust linear regression made with gas-rich galaxies and the grey dotted line corresponds to a regression done with all galaxies. Parameters of the regression fits are given in Table 4. The stars indicate the properties of the Milky Way as obtained from Gilmore & Reid (1983) for the scale-heights and Bovy et al. (2012) for the circular velocity.
