Terms: JPL attaches no open licence to these services. JPL's SSD FAQ (https://ssd.jpl.nasa.gov/faq.html#a05) says
that publishing information from the SSD site needs permission - at minimum JPL wants to know what is used and how -
prefers links to its live pages for frequently updated numbers, and places most site content under JPL's copyright
statement. The data were retrieved under the SSD API fair-use policy (https://ssd-api.jpl.nasa.gov/doc/): one request
at a time, identified User-Agent, cached results; the APIs are not embedded in this website.

No endorsement by NASA, JPL or Caltech is implied.

Changes: selection of populations and brightness cuts; numeric text converted to binary64; CAD fullname dropped;
Horizons daily and perihelion/encounter refinement vectors thinned to a node subset that reproduces every omitted
vector within the stated tolerance under cubic Hermite interpolation (Earth-approach hourly vectors kept in full);
all values otherwise as served.
