Comment nous calculons le ciel
Ce qui relève du calcul, ce qui relève de l’interprétation, et comment nous vérifions le premier.
Les positions
Les planètes sont calculées avec Astronomy Engine (modèle VSOP87 pour les planètes, ELP pour la Lune), en longitude écliptique géocentrique apparente, équinoxe vrai de la date. C’est le repère de l’astrologie tropicale occidentale.
La vérification
Nous comparons nos positions à celles du service JPL Horizons de la NASA : dix corps, 35 dates de 1879 à 2050, soit 350 positions. Le plus grand écart mesuré est de 0,30 minute d’arc (Neptune, 2015-08-15 17:00 UT), soit moins d’un centième de degré : invisible dans un thème, où l’on lit au degré. Le résumé par astre et toutes les mesures sont ci-dessous ; un test les recalcule avant chaque mise en ligne, et la mise en ligne s’arrête s’il échoue.

L’Ascendant et les maisons
L’Ascendant est le point de l’écliptique qui se lève à l’horizon est au moment et au lieu de la naissance ; le Milieu du Ciel, celui qui passe au méridien. Les maisons sont calculées en Placidus. Nos tests vérifient la définition elle-même : l’Ascendant calculé doit être à une hauteur nulle, côté est, et chaque cuspide Placidus à la bonne fraction de son arc. Au-delà des cercles polaires, où Placidus n’existe pas, nous passons en Porphyre et l’indiquons.
L’heure de naissance
L’heure locale est convertie en temps universel avec la base des fuseaux horaires historiques (IANA) : heure d’été, heure allemande en zone occupée en 1940-1944, absence d’heure d’été en France de 1946 à 1975. Pour les naissances antérieures à l’heure légale (avant 1891 en France), le calcul utilise l’heure moyenne de la ville de référence du fuseau, avec une marge de quelques minutes.
Les lieux
Les communes et villes viennent de GeoNames (licence CC BY 4.0) : toutes les localités de France et les villes de plus de mille habitants dans le monde, avec leur fuseau horaire.
Ce qui est interprétation
Les textes qui disent ce que signifie Vénus en Scorpion ou Le Bateleur à l’envers relèvent de la tradition astrologique et du Tarot de Marseille. Ils ont été rédigés pour Lunarie. Ils ne sont pas des faits scientifiques et nous ne les présentons jamais comme tels.
Le hasard du tirage
Le jeu est mélangé sur notre serveur avec le générateur cryptographique du système (crypto.randomInt de Node.js). Une lame sur quatre sort renversée. Ni nous ni personne ne choisit ce qui sort.
