WebNov 29, 2024 · Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an “isochron”) by means of standard linear regression methods of statistics. The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date. WebThe vicarious methods on which RadCalNet is based have been used successfully since the 1980s for the absolute radiometric calibration of earth imaging sensors. Work at multiple sites showed that automated instrumentation could provide SI-traceable, absolute radiometric calibration of on-orbit sensors with known, and peer-reviewed, uncertainties.
