To determine

The data in below figure shows the Doppler shifts of emission lines from gas at a distance of 60 light-years from the center of the galaxy M87. Let us assume that the emission lines are observed from gas 30 light-years from the center. How would once expect the Doppler shifts of those lines to be different, supposing that the gas is orbiting a supermassive black hole. Also, what about the gas at 120 light-years from the center?
