Calculation standard

Astronomy Engine supplies geocentric true-ecliptic positions. Lúmina uses the tropical zodiac, Whole Sign houses, Greenwich apparent sidereal time, Ascendant/MC geometry and five major aspects. The Midheaven is displayed as an angle and does not have to coincide with the 10th Whole Sign cusp.
