It uses an ensemble of bright stars (selected for their stable luminosities) as calibrators for the instrument variability. spase://SMWG/Person/Gary.J.Rottman PrincipalInvestigator NSSDC's Master Catalog https://nssdc.gsfc.nasa.gov/nmc/experiment/display.action?id=2003-004A&ex=3 Information about the SOLSTICE (SOlar STellar Irradiance Comparison Experiment experiment on the SORCE mission.
