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.
