By measuring the Doppler shift in a stellar spectrum, astronomers can determine the orbital velocity of the Earth, the radial velocities of stars, and the Earth's orbital radius (the astronomical unit). In this exercise you will use actual astronomical observations (spectra) of the star Arcturus (α ...
