Public Data Use Policy
Data retrieved from the Mikulski Archive for Space Telescopes (MAST) are part of the public domain and need no explicit permission for use, with the exception of proprietary data. We take care that these proprietary data are only provided to those who have proprietary rights. No explicit permission is needed for the use of MAST tools. Please acknowledge NASA and MAST when using data retrieved from MAST.
Publication of Archival Research Results
Although there is no cost involved in retrieving data from MAST,
researchers are requested to include an acknowledgment (as shown below)
in any publications that make use of data obtained from MAST:
"Some/all of the data presented in this paper were obtained from the
Mikulski Archive for Space Telescopes (MAST). STScI is operated
by the Association of Universities for Research in Astronomy, Inc.,
under NASA contract NAS5-26555. Support for MAST for non-HST data is
provided by the NASA Office of Space Science via grant NNX09AF08G and by
other grants and contracts."
In addition, publications of research supported by an STScI grant
must carry the following acknowledgment:
"Support for this work was provided by NASA through grant number ________ from
the Space Telescope Science Institute, which is operated by AURA, Inc., under NASA
contract NAS 5-26555."
Note for Kepler/K2 Users:
Publications based on data obtained from the Kepler project
are requested to include the additional acknowledgment:
"This paper includes data collected by the Kepler mission. Funding for the Kepler mission is provided by the NASA Science Mission directorate."
Note for HLA Users:
All refereed publications based on data obtained from the Hubble Legacy Archive (HLA) are requested to carry the following footnote:
"Based on observations made with the NASA/ESA Hubble Space Telescope, and obtained from the Hubble Legacy Archive, which is a collaboration between the Space Telescope Science Institute (STScI/NASA), the European Space Agency (ST-ECF/ESAC/ESA) and the Canadian Astronomy Data Centre (CADC/NRC/CSA)."
The Hubble Source Catalog (HSC) is based on data from the Hubble Legacy Archive (HLA).
Refereed publications making use of the HSC should therefore include the above
footnote for HLA users.
Authors are also asked to acknowledge the "Hubble Source Catalog" in the text
of the paper, and consider a reference to the
Whitmore et al. (2015 – see the HSC FAQ)
paper describing the HSC.
