# Third-party notices

This notice covers the Ephemeris calculation-core and N16-generator
distributions. The project-owned source is licensed under Apache License 2.0.

The source package declares dependencies but does not contain their wheels or
the Python interpreter. Installations obtained from the respective publishers
include their complete license files.

## Binary distributions

Every standalone generator build must include the complete license and notice
files from the exact Python runtime, NumPy, SpiceyPy, CSPICE and packaging-tool versions
embedded in that build. This source-level notice is not a substitute for the
exact binary notice bundle.

If PyInstaller is used, its GPL-2.0-or-later license with the PyInstaller
bootloader exception permits distribution of the generated application without
requiring the application itself to be GPL licensed. The license and exception
must be included in that binary package.

No Find_Orb source, executable or library is part of the calculation-core or
N16-generator distribution.
