00readme.txt 5-oct-2017 by Alois Treindl last update 4-aug-21 This download area contains the Free Edition of the SWISS EPHEMERIS. About the Swiss Ephemeris: Swiss Ephemeris is a software toolbox for programmers of astrological software. It is of little use for a non-programmer The test programs SWETEST.EXE and SWEWIN.EXE come with it as demonstration programs for programmers to show them how they can call the SE functions. swetest.exe can be used to compute complete natal horoscopes as textual output. Programmers all over the world have started to build SE into their software. SE ist built according to the highest standards of precision available in astronomical data. It is able to reproduce the ephemeris data in astronomical standard books up to the last printed digit. Detailed information is available at https://www.astro.com/swisseph or in the documentation files included in the distribution. Description of files: ===================== While we have made available many single files, so that they can be viewed directly in a browser, it is much more convenient to download the files in '.zip' or '.gz' format. Except for the single asteroid files, all files in this area available in one of the 'zip' or 'gz' archives and should be downloaded in the archived form for higher speed. LICENSE.TXT The Swiss Ephemeris is published currently under GPL, and alternatively under Swiss Ephemeris Professional License, You must read and accept the license before you download any files. sweph.zip The complete Swiss Ephemeris package for Windows (32bit), except the ephemeris data files. See online documentation at https://www.astro.com/swisseph or in the doc directory for more details. Small sample programs and build-projects are included for - Visual C++ .net 2003 - Visual Basic 5.0 - Delphi 32-bit Note: Visual Basic files may not have been updated and tested, as we currently do not possess a working copy of VB at Astrodienst. swephzip.txt overview of content of the sweph.zip package source code: found on Github https://github.com/aloistr/swisseph These source files will be removed in the near future: src/* swe_unix_src_2.01.00.tar.gz The release of the Swiss Ephemeris source code. A simple Makefile to create a Unix library is included. The unix-readable of the doc directory are also included. The release number is sometimes changing frequently when we are in an active development phase. Sometimes several releases will be available at the same time. It is usually best to take the one with the highest release number. Release 1.67 was the last with the old IAU precission model 1976 (Lieske), old nutation model 1980 (Wahr). It is preserved in swe_unix_src_1.67.tar.gz and sweph_1.67.zip doc/* swisseph.docx Feature Documentation, MS Word format swephprg.docx Programmer's Documentation, MS Word format [there are also PDF and HTML versions of these files] All files are also contained in the swe_src_..gz archive. ephe Directory with binary ephemeris files. jplfiles Directory with files in JPL ephemeris format. This directory can only be accessed via ftp, not via http.

This is a 32-bit Console mode application. To get information about the many features of this program, run swetest -? > out.txt and print the file out.txt, or view it with your text editor. This is just a sample to demonstrate the precision of the ephemeris, and to show the typical use of a few calls. It is possible to use SWEWIN and SWETEST without the ephemeris files. If the program finds no ephemeris files, it uses the builtin analytical ephemeris which provides "only" a precision of 0.1 arc seconds for the planets and 3" for the Moon. No asteroids will be available, and no barycentric option can be used. The SWISS EPHEMERIS can be licensed by programmers to include this calculation engine in their software.
