The DeLuce ayanamsa, developed by Robert DeLuce, is a sidereal system used by some Western astrologers. It represents an alternative approach to measuring the precession of the equinoxes and provides a different perspective on planetary positions in the zodiac.

The Porphyrius house system, named after the 3rd-century philosopher Porphyry, is a quadrant system that divides the space between the angles (Ascendant, IC, Descendant, MC) into three equal parts. It is one of the oldest house systems still in use today.
