The NRLMSISE-00 model this crate implements is the work of Mike Picone, Alan
Hedin and Doug Drob at the US Naval Research Laboratory. It is believed to be
in the public domain as a work of the US Government under 17 U.S.C. 105; NRL
attached no explicit license to it. The coefficients compiled into this crate
are the model's own, and the MIT license above covers this implementation of
it rather than the model.

MSIS is a registered trademark of the Government of the United States of
America, as represented by the Secretary of the Navy. It is used here only to
identify which model this crate implements, which is nominative fair use. This
crate is not endorsed by or affiliated with NRL or the US Navy.
