Data for: "Sputter Yields of the Lunar Surface: Experimental Validation and Numerical Modelling of Solar Wind Sputtering of Apollo 16 Soils"

Introduction

This data repository contains the data behind the figures of the manuscript entitled "Sputter Yields of the Lunar Surface: Experimental Validation and Numerical Modelling of Solar Wind Sputtering of Apollo 16 Soils". The CC-BY licence applies to all data files. 

Figure 2

Data files behind Figure 2 (sputter yields for flat samples) have names starting with "Fig2a" and "Fig2b", indicating data for hydrogen and helium irradiations, respectively. The rest of the filename coincides with the labelling of the Figure.They are organised as comma separated value (CSV) files, where the first line gives the names and units of the columns. For this Figure, data are given in both units amu/ion and atoms/ion, corresponding to both axes of the Figure. 

Figure 3 and Ejecta Angular Distributions

Ejecta angular distributions as measured by the catche QCM technique are given by the files starting with "Angular_emission", where the incidence angle, the projectile species and the sample type are denoted by the rest of the filename. Data are organised as CSV files where the names of the columns are given in the first lines. Angles are measured in degrees, catcher mass yields (mass deposited onto the catcher QCM normalised per incoming ion and detector solid angle) as well as the absolute errors are given amu/ion.

Data are made available for H and He under both 60° and 45° incidence for both sample types in the repository. In the manuscript, only 60° incidence of 4 keV He is shown for illustratory purposes. To recreate this Figure 3, the data are stored in "Angular_emission_60deg_He_rough.dat" and "Angular_emission_60deg_He_flat.dat".

Note that for the hydrogen case, data are given normalised per H2 ion.

Figure 4

Data that occurs for the first time in Figure 4 is stored in files starting with "Fig4a" and "Fig4b", respectively. The rest of the naming convention follows the labelling from the Figure legend, allowing to uniquely identify the data sets. Some data occur first in Figure 1. We refrained from uploading these data sets a second time. 

Figure 5

No new original data are presented in Figure 5. Data that was created and analysed for this study was already shown in the previous Figures. Data from other publications are clearly identified in the text. We do not upload these data from different publications in this repository. Instead, the interested reader is referred to the original publications.

Introduction

本数据仓库包含题为《月球表面溅射产额：阿波罗16号土壤太阳风溅射的实验验证与数值模拟》的手稿中各图背后的数据。所有数据文件均适用CC-BY许可证。

Figure 2

图2（扁平样品的溅射产额）对应的数据集文件名称以"Fig2a"和"Fig2b"开头，分别代表氢辐照和氦辐照的数据。文件名其余部分与图中的标注一致。这些文件采用逗号分隔值（CSV）格式，首行给出各列的名称及单位。本图数据同时提供原子质量单位/离子（amu/ion）和原子数/离子（atoms/ion）两种单位，分别对应图的两个坐标轴。

Figure 3 and Ejecta Angular Distributions

通过收集器石英晶体微天平（QCM）技术测量得到的溅射物角分布数据存储在以"Angular_emission"开头的文件中，文件名其余部分表示入射角、入射粒子种类及样品类型。数据采用CSV格式，首行给出各列名称。角度单位为度，收集器质量产额（沉积在收集器QCM上的质量除以入射离子数与探测器立体角的乘积）及绝对误差的单位均为amu/ion。仓库中提供了两种样品类型在60°和45°入射角下H和He的数据。手稿中仅展示4 keV He在60°入射角下的数据作为示例。重建图3所需的数据存储在"Angular_emission_60deg_He_rough.dat"和"Angular_emission_60deg_He_flat.dat"文件中。请注意，氢的数据是按每个H2离子归一化的。

Figure 4

首次出现在图4中的数据分别存储在以"Fig4a"和"Fig4b"开头的文件中。其余命名规则遵循图注中的标注，可唯一识别各数据集。部分数据首次出现在图1中，我们未重复上传这些数据集。

Figure 5

图5未呈现新的原始数据。本研究生成并分析的数据已在前述各图中展示。来自其他文献的数据在文中已明确标注。本仓库未上传这些来自不同文献的数据，感兴趣的读者请参考原始文献。
