  • Precise calculations of Sun, Moon, planets, Chiron, the lunar node, Lilith (Black Moon), ascendant, midheaven and other houses (Koch, Placidus, Regiomontanus, equal, Campanus, Porphyrius) between 5000 BC and 3000 AD (ephemerides of Astrodienst Zürich); as well ecliptical longitude as latitude, right ascension and declination, speed and distance from the Earth; distribution of elements, triplicities and hemispheres; all possible aspects (up to 40 definable); two-dimensional angles; midpoints; 10 Arabic points; partner comparison (mutual aspects, 2 composite horoscope versions according to Meyer); prediction techniques (transits, secondary progressions ("1 day = 1 year" system), primary directions according to the true solar arc) for one moment or in a chronological list, finding constellations like solar or lunar returns,...
  • Graphic representations: a clear chart wheel (also harmonics) with aspect grid, transits etc. or partner around the circle (with animation); graphic ephemerides (as well classical as circular; the unique linear representation patented by E.V. Flückiger; also unique: "transit concentration graphs": the addition of complex transit patterns (e.g. your self defined "love graph", "business graph" etc.) and "model graphs" (see further).
  • Horoscope interpretation: very extensive possibilities to define your own delineation rules according to your personal experience, from simple to complex combinations, variables etc., also for transits, etc. Sample interpretation files are included (element distribution, ascendant, planets in signs and houses, aspects; factors based on scientific research; Chiron; all major transit aspects; most important partner aspects; different texts in english, flemish (dutch), german, french and spanish).
  • Database: Paradox tables in which natal, event and relationship data can be stored. Import/export of AAF files. Import of txt tiles with e.g. stock market data.
  • Features that are useful for research: extensive statistical queries are possible (e.g. show all horoscopes that have Venus in fire and ascendant trine or sextiel with Jupiter, or: select all events where Pluto transits the Moon, or: select all man-man relationships having mercury square mercury, etc.), also overviews and comparisons with reference files (that can be generated automatically for natal and event data), study of variables (horoscope properties),...
    UNIQUE: Cycle analysis and empirical models: if you entered property values for a big amount of horoscopes (like e.g. IQ, math grades, number of children, gold price,...) you can study extensively their relationships with astrological cycles, and create mathematical models for them (without having to be a math expert). The applications are numerous: e.g. help in your search for the ideal partner, prediction of stock markets, searching the best period for business/love/... Some sample models (love life and general condition, attraction to other persons) come with the program.
  • Atlas: expandable file of places (>34000) and time regulations; quite complete for W-Europe. Places can be viewed on a map and read from the ACS-atlas (not included).
  • Output: to printer, clipboard, RTF, GIF and bitmap files.

Support: extensive help file, assistance by telephone or e-mail if necessary. We also give astrology courses (at home/by correspondence).

Extensions: new versions come regularly (small update fee). We also have separate modules with extensive interpretation texts written by several authors. Custom made adaptations are also possible.

VISTA users! Bill Gates seems to assume these days that the average pc users is an imbecil who can't install anything himself. That's why you may get a very obscure error message like: "Network initialization failed. File C:\PDOXUSRS.NET. Permission denied."
Unfortunately I can't change anything about the stupid overprotection of Windows Vista... very annoying! What you can do is this: either login as "Administrator", either you rightclick the Radix-icon, and select "properties". Then click the tab "Compatibility", and check: "Run this program in administrator mode." and click OK. Now everything should work normally...
