Description
The Hypatia Catalog is a compilation of abundance measurements from 84 literature sources for FGK stars within 150pc of the Sun. The full, raw, un-reduced catalog contains +3000 stars and can be found with the online journal paper. Provided here is the reduced catalog where stars are excluded if 1) they are probable thick-disk stars per Bensby et al. (2003A&A...410..527B, Cat. J/A+A/410/527) and 2) the spread in the compiled measurements for a star in either [X/Fe] or [Fe/H] is larger than the respective error in cases where multiple groups measured the same element in the same star. When abundance determinations were well agreed upon by multiple sources (or when the spread was less than the respective error), the median value of those measurements is found in the machine readable table here. In addition, all abundances here were re-normalized to the Lodders et al. (2009, Landolt-Bornstein-Group VI Astronomy and Astrophysics Numerical Data and Functional Relationships in Science and Technology Volume 4B: Solar System, ed. J. E. Trumper (Berlin: Springer), 44) solar abundance scale. Please see the main paper for more details. To facilitate use of the Hypatia Catalog, the reduced abundance determinations have been provided in this machine-readable format. However, there are two caveats which must be addressed. To begin, Hypatia is a three-dimensional catalog and placing it in two-dimensions created limitations, specifically for [Fe/H]. As an example, if five literature sources measured abundances in a star, then there are five [Fe/H] values. However, if only two of those five measured [X/Fe] within the star, then only the median of the two corresponding [Fe/H] values were used to produce the [X/Fe] Figs. 5-30 in the paper. Rather than give unique [Fe/H] determinations for each element with only the corresponding [Fe/H] values, the median of *all* [Fe/H] measurements are given in the FeH column. Per the example, we used the median of all five [Fe/H] measurements. Since elements with spreads larger than respective error are not included, we found that using all of the well agreed upon [Fe/H] measurements to be a conservative choice. Second, Hypatia is an ever-growing database where new measurements will be incorporated as they are released. We have made some small but important updates to the machine readable table. These two caveats only slightly affected the abundance results as compared to the figures in the paper and did not alter the main results and discussion of the paper. Inclusions of more recent surveys and major changes to trends will be addressed in subsequent publications and will be made available online. It is our hope to put all of the abundance data in a flexible database format in the near future.
