ephcom-2.0.2 has been released

The ephcom-2.0.2 software package that gives users convenient access to the JPL ephemerides, has been released. Those ephemerides (which are available in uncompressed form at ftp://ssd.jpl.nasa.gov/pub/eph/planets/ascii and in compressed form at http://sourceforge.net/projects/timeephem/files/Compressed%20Ascii%20JPL%20Ephemerides\) represent mankind's best knowledge of the positions and velocities of all major bodies of the solar system over centuries (short ephemerides) and millennia (long ephemerides). The ephcom2 software allows the user to manipulate (e.g., convert from compressed or uncompressed ascii form to binary form) as well as interpolate (i.e., provide results at a given time) those ephemeris data in a well-documented (see http://timeephem.sourceforge.net/documentation.php\) way.

The "ephcom2" development effort is a subproject of the Time Ephemerides Project (http://timeephem.sourceforge.net) and also a revival of the "ephcom1" development effort which was last released in May 2004 at ephemeris.com by Paul Hardy. The ephcom-2.0.2 release represents a substantial (some 120 commits for 2.0.1 and an additional 50 commits for 2.0.2) improvement on the ephcom1 software package that was last released in 2004 at http://ephemeris.com. Details of those improvements are available at http://timeephem.sourceforge.net/ephcom2.php. The ephcom-2.0.2 software release, which is licensed under the LGPL, may be downloaded from http://sourceforge.net/projects/timeephem/files/ephcom2. That same location also gives access to ephcom-2.0.2 release notes and the detailed ChangeLog.
