Indexes

Index Definition Description
idx_IsolatedStarStellarMotions_isolated_star_id isolated_star_id Unique index on the isolated_star_id column.
idx_IsolatedStarStellarMotions_referenceId referenceId Non-unique index on the referenceId column; accelerates retrieval of stellar motions for reference objects.
