Data for: Dating a Martian Meteorite with 20 Ma Precision Using a Prototype In-Situ Dating Instrument

These two excel data tables contain the reduced CODEX LARIMS data required to reproduce our Zagami isochron diagrams for February and September 2019 data acquisitions. Each excel file has a header explaining each column. Each spot measurement on Zagami is recorded as a row, with a filename to allow us to identify the original raw data if needed, the date acquired, the measurement position on the sample, the integrated peak areas, the 1-sigma standard error uncertainties, and correlation coefficients.这两份 Excel 数据表包含了用于重现2019年2月和9月数据采集的Zagami等时线图所需的缩减版CODEX LARIMS数据。每个Excel文件均包含解释每列的标题。Zagami上的每个点测量数据均记录为一行，包括用于识别原始原始数据的文件名、采集日期、样品上的测量位置、积分峰面积、1-σ标准误差不确定性和相关系数。
