## SPK type-21 validation reference

The managed SPK type-21 reader follows the public NAIF SPK specification and
was validated against CSPICE through SpiceyPy. Its implementation was also
cross-checked with `spktype21` version 0.1.0 by whiskie14142, distributed
under the MIT License:

https://github.com/whiskie14142/spktype21

The complete MIT licence shipped with that package is reproduced as
`SPKTYPE21-MIT-LICENSE.txt`.

Neither SpiceyPy, CSPICE, `spktype21`, jplephem nor Python is embedded in or
required by the released N16 CLI applications.

## Astronomical data

The applications do not contain precomputed N16 states or object-specific
Horizons SPKs. They download those data from JPL Horizons only when the user
starts generation. The downloaded and locally generated data are not
relicensed under Apache License 2.0. See `DATA-SOURCES-AND-TERMS.md`.
