For a complete breakdown of all catalogs (with > 20 stars) included in the Hypatia Catalog and Hypatia Catalog Database, please download this file, the components of which can be found in Hinkel et al. (2014, 2016, and 2017). In the header, “S/N” is signal-to-noise report by the literature source, “λ Range" is the wavelength coverage, "Stellar Atmo" is the stellar atmospheric model, "Eq. Width" is the package used to determine the equivalent width, "CoG or SF" designates whether the group used a curve-of-growth or spectral fitting technique where the package is specified in the former case, the "Solar Scale" is the solar normalization used by that group (differential analysis is cited where applicable), and "Num. of Fe I/II lines" lists the number of Fe I and Fe II lines. While this accumulation of telescope information, reduction packages, and overall technique was done with the best intentions, errors may arise so please check the original source for verification. Please email hypatiacatalog@gmail.com with any questions or concerns.
Per the ionization states, while some catalogs measured only one ionization state when reporting an abundance determination, a number of catalogs combined the abundances from multiple ionization states. In Hypatia, an abundance of [X/Fe] means that a catalog measured the neutral state, a combination of neutral and ionized state(s), or it was not specified. Whenever a catalog specifically mentioned it was only measuring the singly ionized state, we demarcate it as [X II/Fe].
The handling of binary stellar systems has been updated (Oct 2021). Now, if each component has a unique SIMBAD name and separable stellar spectra, then the abundances from both stars can be found within the Hypatia Catalog.
Finally, the Hypatia Catalog and Hypatia Catalog Database were named for Hypatia of Alexandria, one of the first known female astronomers. She was strong-minded, independent, and well respected by both the people and local officials. Socrates Scholasticus once said of her, “For all men on account of her extraordinary dignity and virtue admired her the more.” For more information, please go to this page, where more resources can be found.
