In order to find the radial velocity at that point, you need to take the velocity of the last value on the line of nodes and subtract the velocity from the center point in order to find the true radial velocity. That means, I did:  $\textrm{ True V_r}$ = $5119 \textrm{ km/s}$ - $4994 \textrm{ km/s}$ = $175\textrm{ km/s}$
