 Dear Stanislas,
 Those files are considered “Public Domain”, so you won’t need any license and
 there will be no copyrights issues.  However, if you do use these files and
 have the option to reference, please refer the SSD site.  If you are using
 specific files, e.g. DE440, please reference the corresponding published file,
 such as:

 Best,
 RP

    Hello, and thank you for making available ephemerides to the public. My
    question is concerning the downloadable data files for ephemerides, both in
    ASCII and binary format (and also, the related source code found at the same
    place). Are those files considered "Public Domain", or do they have any
    other license, or legal restrictions, copyrights, etc? Can you provide a
    link, or document, detailing that subject precisely? I have not found
    information even in the FAQ... Thanks for your attention, looking forward
    to your answer.
