0125705LudwigThis grant provides support for refinements to the widely-used Isoplot/Ex, a MS Excel-based computer program used for reduction and evaluation of radiogenic isotope data. The program will be expanded to include several new capabilities including: 1) a Bayesian + Monte Carlo approach for improving the precision of radiometric dates from a sequence of stratigraphically-constrained beds; 2) a method for logical, statistical, and graphical integration of the two main Ar-Ar age-approaches (stepwise-release age-spectra and Ar-Ar isochrons); 3) a Gaussian unmixing module to enable quantitative evaluation of age-suites involving multiple age-components; 4) code revisions to maintain compatibility with new versions of Excel and eliminate bugs as they are detected; and 5) expansion and revision of the Isoplot User's Manual to increase clarity and teaching effectiveness.***

0125705 Ludwig该基金为改进广泛使用的Isoplot/Ex提供支持，Isoplot/Ex是一种基于MS Excel的计算机程序，用于减少和评估放射性同位素数据。 该计划将扩大到包括几个新的能力，包括：1）贝叶斯+蒙特卡罗方法，用于提高一系列地层约束床的放射性测年精度; 2）两种主要Ar-Ar年龄方法的逻辑，统计和图形集成方法（3）高斯混合分解模块，用于定量评价多年龄组分的年龄组; 4）修改代码，以保持与新版本Excel的兼容性，并在发现错误时消除错误;以及5）扩展和修订Isoplot用户手册，以提高清晰度和教学效果。
