Scientific paper

A group of 248 micrometric observations of 104 double stars are presented, forming the second series of a program carried out at Córdoba with a 30 cm refractor. Usually neglected IDS pairs south of -60° are selected for observation, most of them having been measured only one or two times previously. The measurements are compared with all the earlier observations to derive estimates for the personal equation in P.A. and separation, and the nature of many pairs is discussed by making use of catalogue proper motions.
