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. .
