Grand Trines Study
The Grand Trines Study generates an event whenever three transiting bodies form a Grand Trine: a triangular configuration in which each body forms a 120° aspect with the other two, within a user-defined orb.
Stelliums Study
The Stelliums Study generates an event whenever three transiting bodies are conjunct within a user-defined pattern orb. Stelliums concentrate planetary energy at a single point on the zodiac.
T-Squares Study
The T-Squares Study generates an event whenever three transiting bodies form a T-Square: two of the three are in opposition and the third is square (90°) the other two, within a user-defined pattern orb.
Yods Study
The Yods Study generates an event whenever three transiting bodies form a Yod: two bodies are sextile (60°) one another, and both form a quincunx (150°) to a focal body. The focal body is the apex of the Yod's pointing finger.
