Gravitational Wave Open Science Center


Timeline technology provides instant access to time-based metadata on scales from seconds to centuries. Timeline is developed by the Gravitational Wave Open Science Center, which is supported by the U.S. National Science Foundation.

Welcome to Timeline. This page provides information on when LIGO was collecting science mode data, as well as data quality classifications and injection times.
