NESVORNY SYNTHETIC FAMILY NUMBER * Family number assigned for the purpose of the Nesvorny family analysis based on synthetic proper elements. Family numbers in the 400's refer to inner belt families, in the 500's to central belt families, and in the 600's to outer belt families. High inclination families from synthetic proper elements have family numbers in the 700's for the inner belt, the 800's for the central belt, and the 900's for the outer belt.	NESVORNY SYNTHETIC FAMILY NAME * The name of the asteroid family in the Nesvorny family analysis based on synthetic proper elements. The family name is based on the name or provisional designation of the largest member of the family.
