The EROS Archive is an implementation of catalogues of the EROS Project. The EROS (Expérience pour la Recherche d'Objets Sombres) Project's main objective is the search and the study of dark stellar bodies, so-called "brown dwarfs" or "MACHOs" which belong gravitationally to our Galaxy. This is made possible by their gravitational microlensing effects on stars in the Magellanic Clouds.
