Fig. 1. The peak H I surface brightness map (green colour) and the Halpha image (red colour) for the LMC

Fig. 2. The deprojected rotation curve for the LMC based on the median-smoothed H I 1st moment map (+) (out to 3.2 kpc) and the carbon-star data of Kunkel et al. (1997) (Box) (out to 8 kpc, only) and assuming an inclination of 33°. The solid line is the total predicted rotation curve constructed from the following components: (a) the H I mass distribution, based on the data of Luks & Rohlfs (1992) and a 30% He I contribution (dotted line); (b) the R stellar light distribution, based on the data of de Vaucouleurs (1958), and M/L_R = 1.8 (dashed line); and (c) a pseudo-isothermal dark halo with core radius 2.5 kpc, and central density 0.009 M_sun pc^-3
