CCD astrometry and instrumental $\Delta V$ photometry of visual double stars - V. Differential measurements of pairs with angular separations 1″ to 4″
1999
We present angular separations, position angles and instrumental magnitude differences of 83 visual double stars with angular separations around two arcseconds. Our observations were made by means of a CCD detector attached to the Kryonerion 1.2 m telescope. 12 of them are common proper motion stars and their components should therefore be stars of common origin.
