%description
Plots U-Pb data on Wetherill and Tera-Wasserburg concordia diagrams.
Calculates concordia and discordia ages. Performs linear regression of
measurements with correlated errors using 'York', 'Titterington', 'Ludwig'
and Omnivariant Generalised Least-Squares ('OGLS') approaches. Generates
Kernel Density Estimates (KDEs) and Cumulative Age Distributions (CADs).
Produces Multidimensional Scaling (MDS) configurations and Shepard plots
of multi-sample detrital datasets using the Kolmogorov-Smirnov distance as
a dissimilarity measure. Calculates 40Ar/39Ar ages, isochrons, and age
spectra. Computes weighted means accounting for overdispersion. Calculates
U-Th-He (single grain and central) ages, logratio plots and ternary
diagrams. Processes fission track data using the external detector method
and LA-ICP-MS, calculates central ages and plots fission track and other
data on radial (a.k.a. 'Galbraith') plots. Constructs total Pb-U, Pb-Pb,
Th-Pb, K-Ca, Re-Os, Sm-Nd, Lu-Hf, Rb-Sr and 230Th-U isochrons as well as
230Th-U evolution plots.
