Hello all,
After seeing so much interest in packaging XEphem for the future, I am moved to release it under the MIT Open Source license. To clearly delineate the heritage, I have bumped the version to 4.0.0. You can download it from my usual XEphem home page at . I only changed four files from 3.7.7 to reflect the change in terms:
Copyright
INSTALL
README
versionmenu.c
XEphem needs your help. In particular note I have not incorporated the recent patches by Lutz M?ndle in the contrib section. That would be a good place to start. In general, I can think of at least the following that need attention.
Jupiter and Saturn moons ephemerides polynomials expired in 2020 and will now rapidly grow inaccurate.
Pluto's osculating elements
Magnetic declination model
Delta T model
external access to data and images
updated field stars databases
browser help connections
Finally, let me say Thank You to everyone who has used XEphem. I look forward to seeing where others can take it in the future.
Best wishes to all,
Elwood Downey
