Abstract

Ground-based photometry of three ROTSE contact binary systems was analyzed using the Wilson-Devinney method. One system with a very low mass ratio below q = 0.06 and one with high mass ratio with a complete eclipse and edge-on inclination were found and represent candidates for further study.
