I've been trying this for 3 hours and I'm getting nowhere. These are the graphs I made for Hydrogen Intensity vs Frequency for a radio telescope that transits the sun and galactic arms of the galaxy.

I need to find the rotation speed of the Earth and the galactic arms. So I know I need to measure the doppler shift ...but my problem is, I don't know which spikes correspond to what. What spikes are from the sun or local space and which are from the galactic arms.
Anybody please help?
