THE VISITOR GRAVITY COULD NOT FIT Source and rights notice, checked 2026-09-22 The numerical files are independently structured factual extracts and calculated geometry, attributed below. No blanket open licence is claimed for the sources. The original Nature PDF, XLSX bytes, worksheet presentation, figures and table images are not distributed. Scientific measurements and their published presentation are different things; this notice does not purport to clear all database rights or contractual restrictions in every jurisdiction.

Terms read: https://support.nature.com/en/support/solutions/articles/6000080095-author-copyrights-information Used here: measured numerical coordinates, errors, accept flags, row identities, published numerical residuals for an explicitly separate audit, transcribed spacecraft coordinates (Extended Data Table 2), and the 53 printed ground positions and errors of Extended Data Table 1 (ed-table-1.json), transcribed by two OCR passes at different resolutions and by eye. Converted into an original numerical schema. The short quoted detection statement is attributed in the page. The factual-extraction distinction is described by the U.S. Copyright Office: https://www.copyright.gov/help/faq/faq-protect.html It is not a licence for reproducing publisher presentation. No source images are adapted, and no permission from the publisher is represented as having been given.

Used here: calculated numerical state vectors and gravitational constants, not reproduced website presentation. The API fair-use policy requires sequential, cached requests and prohibits embedding the API in a website. The page makes no upstream request. The FAQ asks users wishing to publish site information to seek permission and prefers links; this work links the site and distributes its own factual geometry extract, not the website. No blanket public-domain or open licence for JPL website material is asserted. JPL's image policy is not treated as a licence for non-image data. No endorsement is implied. Minor Planet Center, List of Observatory Codes, read on 2026-09-22: https://minorplanetcenter.net/iau/lists/ObsCodes.html Used only to name the station codes quoted on the page (703 Catalina Sky Survey, F51 Pan-STARRS 1, J04 ESA Optical Ground Station, 568 Maunakea, 309 Cerro Paranal, 246 Klet). Nothing from the list is redistributed. MPC ground-station geometry is incorporated through JPL's observer calculations. No MPC database replica, bulk observation feed or catalogue correction grid is redistributed. The replication-service terms were read: https://sbnmpc.astro.umd.edu/MPC_database/replication-info.shtml Those terms restrict that service to internal purposes and require identification of modified products if redistributed.
