Rotation curve (top) and median vR (bottom) of the LMC. The assumed values for the centre-of-mass velocity and orientation of the disc (i and Ω) are taken from a fit to all stars within angular radii ρ < 3° of the LMC centre. Angular distances and velocities given on the lower and left axes have been converted to real-space values on the upper and right axes assuming a distance to the LMC of 50.1 kpc (Freedman et al. 2001). The points shown in the upper panel are derived from observed line-of-sight velocities of old and young stars by van der Marel & Kallivayalil (2014, their Table 4.)
