Line-of-sight velocity (in the frame of the local standard of rest) to the MS in the 9:1 SMC model. Colors show relative density of gas on a logarithmic scale. The H I velocity gradient from Nidever et al. (2010) is shown as the dark contours. The LMC orbit is shown as a solid black line while the SMC is the dashed black line. Blue squares show the position and velocities of the observed LMC and SMC (the center of the LMC is currently at 0° longitude).
