Relative proper motions in systems of the Trapezium type. II
Abstract
The paper deals with the determination of the relative proper motions of seven Trapezium-type systems from photographs obtained with a 400-mm astrograph. The proper motions are catalogued for the systems: ADS 307, ADS 2161, ADS 11 179, ADS 14 338, ADS 14 526, ADS 14 831, and ADS 15 220.
