What is calculated
Mars is one of the seven classical visible grahas. Its calculated longitude is distinct from any later traditional interpretation of its role.
Mars is displayed by sidereal sign, degree within the sign, whole-sign house, nakshatra, and pada. The beta does not turn this coordinate into a predictive reading.
How to inspect the result
Begin with the birth details and calculation method, then read the placement table. A sign label can change near a 30° boundary when the input or ayanamsa changes slightly.
The South Indian chart shows the same sign and house relationship visually. It is a different presentation of the calculated data, not a separate calculation.
