The 7 Jaimini karakas — significators determined by sorting the 7 classical planets by degree-within-sign descending. The planet at the highest degree becomes Atmakaraka (soul); subsequent positions fill the remaining roles in priority order.

Arudha pada for each of the 12 houses. Classical "reflection" formula: distance from house cusp to its lord, then the same distance from the lord. Parashara correction (replace with 10th from lord) when the arudha would collapse onto the 1st or 7th from itself.
