change license
Currently, kepmodel
is licensed under GPL3, which is not a permissive license. Unfortunately, this license is incompatible with the ESA permissive public license (https://essr.esa.int/license/european-space-agency-public-license-v2-4-permissive-type-3).
In practice this means that kepmodel
cannot be a dependency of any code released under the ESA permissive public license. This would, for example, prevent the use of kepmodel
in a public ESA-distributed package that demonstrates how to fit Keplerian orbits to DR4 epoch astrometry.
Permissive licenses that are compatible with the ESA permissive public license are, e.g. MIT, BSD, and Apache.
@Jean-Baptiste.Delisle would it be conceivable to relicense kepmodel
under a compatible license?
