Plots UPb data on Wetherill and TeraWasserburg concordia diagrams. Calculates concordia and discordia ages. Performs linear regression of measurements with correlated errors using 'York', 'Titterington' and 'Ludwig' approaches. Generates Kernel Density Estimates (KDEs) and Cumulative Age Distributions (CADs). Produces Multidimensional Scaling (MDS) configurations and Shepard plots of multisample detrital datasets using the KolmogorovSmirnov distance as a dissimilarity measure. Calculates 40Ar/39Ar ages, isochrons, and age spectra. Computes weighted means accounting for overdispersion. Calculates UThHe (single grain and central) ages, logratio plots and ternary diagrams. Processes fission track data using the external detector method and LAICPMS, calculates central ages and plots fission track and other data on radial (a.k.a. 'Galbraith') plots. Constructs total PbU, PbPb, KCa, ReOs, SmNd, LuHf, RbSr and 230ThU isochrons as well as 230ThU evolution plots.
