The Raman ayanamsa, developed by B.V. Raman, is one of the most respected sidereal systems in Indian astrology. It is similar to the Lahiri system but with slight differences in calculation, making it a popular choice among traditional Vedic astrologers.

The Koch house system, developed by Walter Koch, is a quadrant system that divides houses based on the great circles through the east point and the MC. It is popular in German-speaking countries and among some modern astrologers for its focus on individual birth time accuracy.
