My site is reincarnated as http://sofajpl.com .

There you will find the SofaJpl astronomy DLL, the production release of
the Lunar program, and the beta release of the next Lunar version,
version 4.4.

New in Lunar 4.4:

• it remembers the JPL ephemeris and leap second files from the last
run, as well as the user latitude, longitude, and height

• a "center of light" option for planets (thank you Antoine Couëtte)

• "Horizons compatibility" option to generate coordinates compatible
with the JPL Horizons online calculator

• "solar eclipse" mode to apply the standard semidiameter and
corrections for center of figure in the Astronomical Almanac predictions

• If a lunar distance solution fails to converge in a reasonable number
of iterations, the program warns of possible degraded accuracy but does
not throw an exception.

• quite a few improvements in the output data

The program itself has given complete satisfaction in my tests, but the
documentation in this beta release is not yet adequate.
