Unfortunately this is not always the case for the covariance terms.

The remaining two classes of input formats specify the covariance structure of the data without requiring any actual covariances or correlation coefficients.

The principal aim of this paper is to provide a general overview of the design philosophy and basic operating principles behind the software, rather than a detailed manual of all its components.

Sections 10-15 provide specific details about the Rb-Sr, Sm-Nd, Lu-Hf, Re-Os, Ar, U-Pb, Pb-Pb, U-Th-He, fission track and U-series dating methods.

Examples of this include isochrons, concordia diagrams, age spectra and density estimates.

Implementing these methods in a rigorous and self-consistent manner requires appropriate software.

Geology is, in essence, a historical science in which timing is of the utmost importance.

Geochronology underpins the study of Earth history and puts fundamental constraints on the rate of biological evolution (Chen and Benton, 2012; Gradstein et al., 2012).

For many years, a is a user-friendly toolbox that allows geologists to calculate and visualise geochronological data within a familiar spreadsheet environment (Ludwig, 1988, 1999, 2003a, 2012).
