... Early studies of PMS stars focused on T associations, especially Taurus-Auriga. However, one might expect low mass star formation to be different in OB associations. ... He identified Orion OB1a as the stars northwest of the belt. Orion OB1b is composed of the stars near the belt, including the belt stars and Orionis. ... He finds no perceptible distance change within the Orion OB1b association and finds the distance modulus to be 7.8 and 7.9 for Orion OB1a and OB1b respectively. ...
