The Oriented Scintillation Spectrometer Experiment (OSSE) is one of four experiments on NASA's Compton Gamma Ray Observatory (CGRO) satellite. OSSE was designed to undertake comprehensive gamma-ray observations of astrophysical sources in the 0.05-10 MeV energy range. The instrument also had secondary capabilities for gamma-ray and neutron observations above 10 MeV that are of particular value for solar flare studies. This database table was last updated in August 2005. Some duplicate entries in the table were removed in June 2019. The data in this table was supplied by the CGRO Science Support Center.
