Review

Purpose: To illustrate how the velocities of galaxies are measured using a photon-counting spectrograph. To show how this information, along with estimates of galaxy distances (from their integrated apparent magnitudes) yields the classic Hubble redshift- distance relation. To determine the value of the Hubble parameter and the expansion age of the universe.
