Abstract
I studied the membership of stars near the Segue 3 cluster. Using position and proper motion data I calculated membership probabilities for each source in the area near Segue 3. I found an excess in source density near the cluster center in both position space as well as proper motion space. By fitting an exponential model to the density as a function of radius and comparing the motion of sources, I calculated membership probabilities based on distance to the cluster center as well as differences in motion to find the most likely cluster members.
