Development and Documentation of a Computer Program for Noble Gas Data Reduction

[125758]在伯克利地质年代学中心（BGC）和其他实验室，一个用于分析40Ar/39Ar数据的广泛数据缩减程序已经处于beta测试阶段。这笔赠款的支持增加了重要的高级数据解释功能，以及制作适合公众传播的详细文件。这些功能包括：1)利用Arrhenius标绘程序对氩气扩散实验进行评价；2)将步进加热光谱直接与等时线分析联系起来，从而可以根据等时线MSWD进行平台的识别，并将非零截取点直接反馈到平台程序中，从而生成合适的平台年龄和综合年龄；3)可选择以标准格式输入光谱仪数据的文本文件；4)非ar Noble气体的数据简化能力。该计划的扩展用户支持将包括详细的，冗余索引的pdf格式手册和在线支持，以帮助屏幕的形式以及Mac OS系统上的气球帮助（高达9.1）和Mac OS x上的工具提示。正如设想的那样，该手册将适合作为同位素地质学研究生级课程的网络可用教学工具

0125758DeinoAn extensive data-reduction program for analysis of 40Ar/39Ar data is already in the beta testing phase at the Berkeley Geochronology Center (BGC) and other laboratories. Support from this grant add important, high-level data interpretation features, as well as producing detailed documentation suitable for public dissemination. These features will include: 1) an Arrhenius plotting program to evaluate argon diffusion experiments, 2) linkage of step-heating spectra directly to isochron analysis, so that the identification of a plateau can be based on isochron MSWD's, and also that non-zero intercepts can be fed back directly into the plateau program to generate appropriate plateau and integrated ages, 3) optional text-file input of spectrometer data in a standard format, and 4) data reduction capability for non-Ar Noble gasses. Expanded user support for this program will include a detailed, redundantly-indexed, PDF-format manual and on-line support in the form of help screens as well as Balloon Help on Mac OS systems up to 9.1, and Tool Tips on Mac OS X. As envisioned, the manual will be suitable as a web-available teaching tool for graduate-level classes in isotope geology.***
