How to get a MAST DOI (persistent data link)

Help us provide a persistent reference to the data you used in writing your manuscript. Choose from these methods to identify all MAST data you used, and create or find a new persistent data link: a DOI. This DOI should be included in the manuscript, which will help readers more easily find your data.

Choose one of the options below to get started:

Does your paper use...

A collection of specific observations? (One or more observations from Hubble, Kepler, GALEX, IUE, etc.)

You should use the the MAST DOI Portal to generate a DOI for the one or more observations. If you wish to reference one or more images, spectra, or time-series data generated by one of our missions (HST, Kepler, FUSE, IUE, etc.) this is the place to go. If you wish to reference data from the Kepler/K2 mission in bulk, see below.

Data from a High-Level Science Product? (CANDELS, K2SFF, etc.)

High-Level Science Products are pre-processed community-provided datasets that already have DOI links, which can be found on the HLSP page next to the name of the product.

A catalog? (Kepler/KIC, GALEX/MCAT, etc.)

At present, we provide a single DOI for each of the following MAST catalogs and surveys.

An entire quarter or campaign from Kepler/K2?

Data from the Kepler satellite are often referred to in large collections, either by quarter, by cadence, or as a whole. Below are links to DOIs for these data collections:

FAQs show/hide

What is a DOI?

STScI now provides journal authors DOIs to create unique persistent links to MAST data. DOI stands for Digital Object Identifier. You may have seen them used in links to scholarly journal articles and in the NASA Astrophysics Data System. DOIs create persistent and unique links to text, web pages, data and other digital resources. Read more about DOIs here:

Why use a DOI?

DOIs provide easy access to specific data sets, providing others fast, efficient, and durable access to your data. Papers with links to data are cited more frequently and non-durable data links tend to fail over time.

How should I reference a data set DOI in my manuscript?

Once your custom DOI has been created or you have selected a DOI for an existing data product or catalog, cite the DOI in your manuscript. This can be done in the “data” or “analysis” section, or wherever else it makes sense in your article. See More DOI FAQs for comprehensive information and recommended AASTeX / LaTeX code.
