... relations

The asymmetry of the candidate members in the m₁ vs. b-y diagram is due to binarity, on the one hand, which in the case of the cool stars always mimics a metal deficiency; and on the other hand to the presence of giants, which are located towards lower m₁ than for dwarfs for the same b-y (Olsen 1984).
