Credits

VOSA uses some external services and theoretical models that you might want to cite or acknowledge if your science benefits from the use of this tool.

You can find below the description and, when appropiate, the bibliographic reference corresponding to all of them.

When you download the results obtained by VOSA two files will be included: info/refs.dat with the references to all the services used to obtain the results and info/refs.bibtex.bib with the bibtex entries corresponding to all those references.
