Measurements of visual double stars collected with the 50-cm refractor of the observatoire denice in1968 and with the45-cm refractor of theobservatoire royal de belgique from 1969 to 1974. (French Title: Mesures d'Étoiles doubles visuelles obtenues - l'observatoire de nice en 1968 (lunette de 50 cm) et avec la lunette Équatoriale de 45 cm de l'observatoire royal de belgique de 1969 - 1974)

Abstract: We present in an electronic form the measurements of the relative positions of 129 visual double and multiple systems performed by Dr E. Van Dessel during the years 1968-1974. In the summer of 1968, 64 measurements of 38 different systems were collected at the Observatoire de Nice. From 1969 till 1974, 295 measurements of 91 systems were collected at the Observatoire royal de Belgique. The original booklet of the observations was put at our disposal for this task performed by one of us (S.R.). In addition, we also present the residuals in the sense (Observed-Calculated) based on the orbits listed in the Sixth Catalog of Orbits of Visual Double Stars (Hartkopf and Mason, 2012). 2
