Scientific paper

A total of 198 micrometric observations of 103 double stars are reported, which form the third series of a program started at Córdoba with a 30-cm refractor. The WDS pairs observed are largely neglected wide systems mostly south of -60°, many of them having only one previous observation. Internal errors are estimated, and all existing measurements of the pairs are used to study the personal equation. Catalogue proper motions are employed to investigate the motion and nature of many of these stars.
